Hi James There are several dates in early copper which are far rarer than catalogues indicate (and a few overvalued dates too) Quality is always better at holding its value so concentrate on buying the best. For investment buy well rounded,centred, quality silver hammered coins.They seem to be popular and always sell for a premium over book price whether on dealers lists,ebay,coin fairs or auction. Gold....can you guess where it is going next....history has shown it to peak and trough....where are we now?
