World oil prices rallied as energy demand was seen to be rising in the United States and China - the two biggest consumers of fuel. Platinum hit the highest level for a quarter of a century as demand for the metal outpaced supply.
Tropical Storm Beta and bird flu fears affected trading of coffee and soya futures respectively.
Wool prices hit the lowest point for five and half years in leading producer Australia, whose dollar rose against its US counterpart.
The Commodities Research Bureau's index of 17 commodities dipped to 321.26 points on Friday from 321.54 points the previous week.
GOLD: Gold prices rose this week as the US dollar weakened against the euro and yen.
"The rally in gold prices continues to be technically driven... with prices gaining on the back of fund buying and dollar weakness," Barclays Capital analyst Yingxi Yu said.
Gold had reached an 18-year high point of 480.49 dollars earlier in October.
A weaker US currency traditionally leads to a rise in the metal's price, as investors switch to a safe-haven.
On the London Bullion Market, gold prices jumped to 470.75 dollars per ounce at the late fixing on Friday from 462.85 dollars the previous week.
SILVER: Silver prices swung higher in the wake of gains won by sister metal gold.
"Silver has the potential to break higher with a breach of the 7.90-dollar level," said James Moore, an analyst for the specialist website TheBullionDesk.com.
On the London Bullion Market, silver prices rose to 7.79 dollars per ounce at the late fixing Friday from 7.60 dollars the previous week.
PLATINUM AND PALLADIUM: Platinum rose to a 25-year high point and palladium reached the best level for a year.
"Platinum remains bolstered by its positive (supply and demand) fundamentals," Moore said. The metal hit 947 dollars per ounce on Thursday, the highest point since March 1980, when it reached more than 1,000 dollars.
Palladium meanwhile struck 227 dollars at Thursday's fixing, the highest fixing level since October 11, 2004.
Looking ahead, Chinese jewellery demand and fund buying would provide further support to palladium, Moore said.
On the London Platinum and Palladium Market, an ounce of platinum rose to 940 dollars per ounce at the late fixing Friday, from 925.50 dollars the previous week.
Palladium climbed to 224 dollars per ounce, from 208 dollars.
BASE METALS: Base metals prices showed mixed fortunes this week, with copper easing after a record run higher.
"The base metals have been trading in two distinct groups recently with copper, zinc, aluminium and lead trending higher, while nickel and tin have been pressing lower," said William Adams, an analyst for the specialist website BaseMetals.com.
However the latter part of the week "showed some sign of convergence with copper pulling back below 3,900 dollars (per tonne) while nickel and tin climbed off their lows".
Copper slipped after rising for the first time above 4,000 dollars last week on strong Chinese demand.
Investors were meanwhile preparing for London Metal Exchange week beginning on Monday. The week-long annual conference in the British capital is dedicated to base metals.
By Friday, three-month copper prices on the LME dipped to 3,841 dollars per tonne from 3,856 dollars the previous week.
Three-month aluminium prices gained to 1,938 dollars per tonne from 1,928.50 dollars.
Three-month nickel prices fell to 11,755 dollars per tonne from 11,925 dollars.
Three-month lead prices dropped to 951 dollars per tonne from 955 dollars.
Three-month zinc prices increased to 1,544 dollars per tonne from 1,473 dollars.
Three-month tin prices slid to 6,250 dollars per tonne from 6,400 dollars.
OIL: World oil prices rebounded as the market began to focus on the upcoming northern hemisphere winter when demand for heating fuel was forecast to jump.
Worries about cold weather hitting the US north-east saw New York crude jump 2.12 dollars on Tuesday to 62.44 dollars per barrel.
However crude futures remain way below the record 70.85 dollars per barrel reached on August 30, after Hurricane Katrina tore through the oil-rich US Gulf of Mexico.
Prices climbed this week also amid signs of higher Chinese demand, analysts said.
Phil Flynn, an energy analyst with Alaron Trading, said that traders' focus "has shifted to distillates and that includes heating oil".
He added: "Winter just seemed so far away last week but sometimes winter can sneak up on you and with frost and snow on the Halloween pumpkin, traders will worry that we will face a long, hard, cold winter.
"And if that is indeed the case we will worry about our supposedly adequate supplies of natural gas and heating oil."
Meanwhile after a drop in Chinese oil demand growth during the first half of 2005, demand from China - the second biggest energy consumer after the United States - appeared to be regaining momentum.
Chinese oil demand growth rose by 6.3 percent during September, compared with the same month one year ago, after a 3.7-percent increase in August, according to estimates by French bank Societe Generale.
American demand was also on the rise, according to Wednesday's crude stockpiles report from the US Department of Energy (DoE).
The DoE said that distillate demand stood at 4.0 million barrels per day in the week ending October 21, while gasoline stood at almost 9.0 million barrels.
That marked a 400,000-barrels-per-day jump in distillates, while gasoline (petrol) demand was unchanged on the previous week.
A barrel of Brent North Sea crude for delivery in December climbed to 59.17 dollars late Friday, from 57.80 dollars the previous week.
In New York, a barrel of crude for delivery in December rose to 61 dollars from 59.31 dollars.
RUBBER: Rubber prices drifted lower in quiet trade.
"It is still low season for supply because of the rains, and demand is routine, doing nothing spectacular," said Rashid Ahmed, a trader with Corrie Maccoll, adding that the market "lacked direction". The raining season traditionally lowers output in Malaysia, Indonesia and Thailand, as farmers have difficulty in collecting latex.
On TOCOM, Tokyo's commodity exchange, natural rubber for December delivery dipped to 190.20 yen on Friday, from 193.50 yen a week earlier.
Singapore's RSS 3 December contract decreased to 166.50 cents on Friday, from 167.25 cents the previous week.
COCOA: Cocoa prices rose amid mounting tensions in major producer Ivory Coast.
"Dangerously volatile political conditions keep speculators at the ready to buy more cocoa," said Refco analyst Ann Prendergast.
Ivory Coast's opposition and rebel ministers boycotted this week's cabinet meeting, claiming that President Laurent Gbagbo's five-year term had come to an end.
However, the UN Security Council has endorsed a decision by the African Union to maintain Gbagbo in his post for 12 months following an aborted October 30 election date, giving the west African country another year to wrap up a long-overdue disarmament campaign.
On the Liffe, London's futures exchange, the price of cocoa for December delivery climbed to 822 pounds on Friday, from 817 pounds a week earlier.
On the New York Board of Trade (NYBoT), the December contract climbed to 1,379 dollars per tonne on Friday, from 1,365 dollars.
COFFEE: Coffee prices fell in technical trade, with limited support from fears that tropical storm Beta would affect crops in major producer Nicaragua.
"Tropical storm Beta, which is due to hit coffee-rich Nicaraguas mainland today (Friday), is providing some support," Sucden analysts said.
"Beta is set to dump up to 20 inches of rain over parts of Nicaragua, Costa Rica, Honduras and Panama, countries that are still sodden from the weeks of rain caused by hurricanes Stan and Wilma."
Beta, the record 23rd storm of the Atlantic hurricane season, threatened Central America with heavy rains and winds as it appeared set to reach hurricane force. On the Liffe, Robusta quality for January delivery fell to 945 dollars per tonne on Friday, from 969 dollars a week earlier.
On the NYBoT, Arabica for December delivery slipped to 98.10 cents per pound, from 105.90 cents.
SUGAR: Sugar futures were little changed. "The market is waiting for some event or catalyst to jolt it out of its range," Prendergast said. By Friday on Liffe, the price of a tonne of white sugar for December delivery stood at 289.80 dollars, from 299 dollars a week earlier.
On the NYBot, the price of unrefined sugar for March delivery stood at 11.69 US cents on Friday, from 11.76 cents a week before.
GRAINS AND SOYA: Grains and soya prices were under pressure, while fears persisted that bird flu might halt demand for the latter.
"Bird flu is putting a cap over soybeans futures as well as corn," said Allendale analyst Joe Victor.
Corn is a major ingredient in the poultry feed, which is a combination of soy meal and corn, he added.
Several cases of the virulent H5N1 virus have been found in south-east Asia and on the fringes of Europe, leading to mass culls of farm fowl.
On the Liffe, the price of a tonne of wheat for November delivery firmed to 69 pounds late Friday, from 68 pounds a week earlier.
On the Chicago Board of Trade, the price of wheat for December delivery dropped to 324.50 US cents per bushel on Friday, from 330 cents.
Maize for December delivery dipped to 197.50 cents per bushel Friday, from 201 cents.
Soyabeans for November delivery slipped to 567.50 cents per bushel on Friday, from 573.50 cents. December-dated soyabean meal - used in animal feed - rose to 169.90 dollars per tonne, from 168.90 dollars.
COTTON: Cotton prices were mixed amid poor export data from leading producer United States. "Cotton futures ended sharply lower on Thursday" as "poor US export sales sparked the sell off", Refco's Prendergast said. Prices had slid more than 2.5 cents on Thursday.
On the New York Cotton Exchange (NYCE), the December contract declined to 52.00 US cents per pound on Friday, from 53.30 cents a week earlier. The Cotton Outlook Index of physical cotton stood at 59.05 cents on Thursday, from 58.45 cents last week.
WOOL: Wool prices fell to the lowest level for five-and-a-half years in major producer Australia, as a stronger Australian dollar made exports more expensive for buyers abroad.
The Australian Eastern index fell to 6.76 Australian dollars per kilo on Thursday, the lowest point since March 2000.
"The Australian wool market finished this week with prices 1.0 percent lower on average," the Australian Wool Industries Secretariat said.
The Australian Eastern index dropped to 6.66 Australian dollars per kilo on Thursday from 6.72 last week.
The British Wooltops index stood at 402 pence on Thursday, from 403 pence the previous week.
