I don't think anything about it because I don't see them. Give me some time to ask my psychiatrist what he thinks. Chris
The quarter you are referring to is probably the only one of its kind for that year and mint mark. Very highly unlikely two Canadian coins made it into the minting process. The coin you want to look for would be from Sanfransisco It is also a proof coin. The likely hood of even finding a proof quarter in circulation is probably next to nothing. Not impossible, but very unlikely
