It's a very kind offer dmw, though I'm not sure if this is the ideal place for it. But maybe one of the members knows someone that might like them.
I suspect Changechecker works on what you'd need to pay to buy a coin. Most dealers have to charge a minimum of a few quid, just to recoup the admin of packing and postage. For things that are essentially face value it's often only economic for collectors if they're buying in bulk .. see ebay.
