NEW YORK/LONDON, Sept 25 (Reuters) - Gold dipped on Thursday but analysts expected fears about the fate of the $700 billion Wall Street bailout plan to support bullion prices.
Physical buying for gold remained strong as investors turned to precious metals as a safe haven amid financial turmoil. The U.S. Mint suspended the sale of some popular gold coins as soaring demand depleted its inventory.
Spot gold <XAU=> was at $873.20/876.20 an ounce at 3:20 p.m. EDT (1820 GMT), down 0.9 percent from gold's nominal Wednesday close at $881. Earlier on Thursday it rose nearly 2 percent to $896.60 an ounce.
It fell more than 2 percent to $862.85 an ounce after the U.S. open as equity markets firmed and traders sold to cover positions related to the expiration of COMEX October gold options on Thursday, said RBC Capital Markets Global Futures Vice President George Gero.
The metal has gained about 20 percent since Sept. 11, when a collapse in the share price of U.S. investment bank Lehman Brothers <LEHMQ.PK> raised questions about the stability of the U.S. and global financial sector.
"Weekends recently have tended to be perilous times," said Nick Moore, commodities strategist at RBS. "There is concern that the weekend could bring fresh concerns about the bailout plan because of political dragging."
The U.S. Congress was close to a deal to approve the package, but investors are wary. [
]Gold is used as hedge against financial chaos.
"Gold prices are rising as the era of loose credit draws to a close and the ensuing global crisis leaves few solid instruments for cautious investors to hold onto," said investment bank Fairfax in a note.
U.S. gold contract for December delivery <GCZ8> settled down $13.00, or 1.5 percent, at $882.00 an ounce on the COMEX division of the New York Mercantile Exchange.
PHYSICAL DEMAND SOARS
The U.S Mint told dealers on Thursday it again was temporarily suspending sales of American Buffalo 24-karat gold one-ounce bullion coins.
In mid-August, a shortage of American Eagle one-ounce gold coins due to "unprecedented" demand had forced the U.S. Mint to temporarily suspend sales of the popular coins.
Coin dealers in North America have reported a surge in buying of bullion coins and other gold products as troubles in the financial markets prompted people to seek a safe haven in precious metals.
Looking ahead, gold should draw support from physical demand in the world's largest consumer India, which is approaching its traditional wedding and festival season.
Also on the agenda is the end of the fourth year of the Central Bank Gold Agreement on Friday.
The World Gold Council said last month around 319 tonnes of gold have been sold so far by the European Central Banks that signed the agreement, out of a quota of 500 tonnes allowed in each year.
"It will be interesting to see how much of the allocation has been taken," Moore said. "It looks as if it could be fully taken up."
While that news may temporarily faze the market, it is unlikely to do any lasting damage to confidence in gold's ability to weather the financial and economic storms.
A measure of investor interest in gold is the record holdings in SPDR Gold Trust <GLD.P>, the world's largest gold-backed exchange-traded fund, which on Sept. 23 hit a record 724.94 tonnes. <XAUEXT-NYS-TT>.
SPDR has seen its holdings increase by 18 percent, or more than 100 tonnes, since Sept. 15.
Platinum <XPT=> was at $1,172.00/1,196.00 from $1,192.50 late on Wednesday, palladium <XPD=> at $230.50/238.50 from $246, and silver at <XAG=> $13.15/13.25 an ounce, down from Wednesday's nominal close of $13.21 an ounce.
