Hi there,
 
	I bought one of the Peter Rabbit 50p silver proof coins for my wife's birthday on the Royal Mint website last year, but have since noticed how people have been selling them for more than 10x the original price on eBay. Out of curiosity, I was wondering whether they are likely to further increase in value in the future? It's nice to think that something I thought was an affordable gift has now become a very expensive one.
 
	Kind regards,
 
	Karl
