The American Revolution Bicentennial coin, issued in 1974, is generally worth its face value of 25 cents. However, its value can vary slightly depending on its condition and whether it has numismatic interest among collectors. In uncirculated condition, it may fetch a small premium, typically ranging from 50 cents to a few dollars. For more precise valuation, it’s best to consult a coin collector or a numismatic expert.
8-2-11>>> The Bicentennial was in 1976 not 1972, if the piece is gold (or plated) and dated 1972 it is NOT a US Mint product. The Mint did not strike any modern gold coins until 1984.

Since it is a one ounce token, you should be able to sell it to a dealer for about $1 under spot (spot = the current value of silver). If it is in brilliant Uncirculated or Proof then you may be able to sell it as a collectible. Rick CCNV2010 on Ebay
There are three different types of gold American Eagles coins. The one ounce coin costs fifty dollars. The quarter-ounce coin costs ten dollars, and the tenth-ounce coin costs five dollars.
The coin has 3.1103 grams of pure gold in it or 1/10th of an Troy ounce.
All US bicentennial coinage has the dual date 1776-1976 not 1973, none of the bicentennial half dollar coins made for general circulation contain any silver or are worth more than face value. Only Proof and collectors coins sold from the US Mint are worth more.
There's nothing called a "commerative" coin. There are COMMEMORATIVE coins, but an coin from 1985 is unlikely to commemorate any major bicentennial. Special coins were minted in 1976 for the 200th anniversary of independence, and others were minted in 1989 for the 200th anniversary of the Constitution.
