What is the value of 1982 princess of wales and birth of Prince William coin?

Answer 1

If such a coin does exist, and I have trawled the Royal Mint catalogues with no success, then its value would depend on the metal used. Typically commemorative coins are struck in either sterling silver or in gold, and have a face value of £5 in modern times. I would think, since such things are notoriously hard to sell, their value would be restricted to the weight of the metal in question, and the selling rate of that same metal per ounce at the time of selling.

Are you sure you are not referring to the coin which was struck in both gold and silver for Prince William's 21st birthday? I have spent hours trying to track down one struck in 1982 and drawn a blank. However, there are sometime unofficial mints, ie those having no affiliation with the governmental Royal Mint, which issue coins. The Franklyn mint is one such. Coins from these sources have little intrinsic value, they are merely worth what somebody is willing to pay at a given time, even though their initial purchase might have been fairly costly.
