Presumably you refer to the bronze medallions designed and produced by 13 year old Daniel Hendy to help assist the farming families effected by the 2001 British "Foot and Mouth" outbreak.
The medallions were originally sold for £6 GBP each, a total quantity of 1,000 medallions.
There appears to be no information available on these medallions, but since there were only 1,000 made, I suggest that they are collectible and have some value beyond their purchase price.
A reputable coin dealer may be able to give a valuation.
It depends on what coin they are. Most of the time, commemorative coins are made in vast quantities for sale to collectors and are worth very little (for example, even Franklin Mint silver coins are worth little more than melt) but it really depends on what it is.
The value of a 1990 Eisenhower gold commemorative coin depends on the condition of the coin. On average the coin would be worth approximately $26.
The value of your coin is probably around (500,000 USD.)
Which one? Post new question.

$330 to $430 depending upon the condition of the coin.
The Royal Mint does not issue Commemorative copper coins. The only Queen Elizabeth II commemorative coin issued in 1953 was the cupro-nickel Coronation Crown.
Since this isn't a legal tender coin, but rather a commemorative medallion, it holds no numismatic value. If the medallion is truly gold, then it definitely has some intrinsic value in metal content, but more than likely it's bronze or brass. In that case, it may have some value with collectors of race memorabilia.
