The precious metal from which the coin is made, and whether it has a “proof” finish can also be a determining factor in valuation. “However, it’s important to remember that not all commemorative coins are made equal,” the auction house added.
“Non-circulating commemorative coins are particularly sought after by collectors due to their aesthetic appeal or rarity value”, so the Platinum Jubilee coin could be a piece worth holding on to. But generally, the rarer the coin, the more valuable it is. “There’s no hard and fast rule” that can be applied to coin valuation, said auctioneers Warwick & Warwick.
Some 50p coins are worth considerably more than their face value, with eagle-eyed collectors, or numismatists, willing to pay huge sums for rare editions.
