I guess not every place has the same type of LCS owners. I am surprised they did not offer for silver content. I know locally the Canadian Olympic coins sell for bullion all day long. the Canadian dollar sets you have, only have 1 silver coin (the special dollar coin) in them and it is only 50% silver worth about $5 or so, the rest of the coins in the set would be worth face value to anyone up here.
the Regina dollars, are these the ones in the clamshells or are they loose? these were offered in 50% silver (in the clamshell) and as a 100% nickel circulation coin (worth face value if you can find someone to buy them)
unfortunately the NCLT market crashed a year or 2 ago, and now everyone has this type of stuff, and nobody wants to buy them.
