Where do I look this up? It isn't listed here: http://www.coinsandcanada.com/coins-prices.php?coin=10-cents-1975&years=10-cents-1953-2013 Although I do have one with that die chip also
Other than coinsandcanada.com, I don't know of a resource for doubled die listings of Canadian coins.
Does anyone know if doubled dies and other die varieties are as sought after in other countries besides the US? Or is this mostly an "American" thing?
