Since this original message was in relation to Canadian numismatic 
references, I am taking the opportunity to ask a couple questions
about Canadian coins:

1) We have all heard much about the "pre-64" US silver, as investment
or survival hoard, or whatever. What is the equivalent in Canadian
coinage? When did Canadian coins drop the silver content?

2) I ended up with some Canadian change, having bought something
while passing through the Minneapolis airport a while back. I just
left it with my pocket change and it got spent at various locations.
However, noticing it made me wonder about how it is treated in
areas close to Canada, which must get a lot of it in circulation.
Even though the Canadian dollar is currently worth somewhat less
than the US dollar, are the coins just treated as equivalent while
in circulation? That is, does a drugstore in Buffalo accept a 
Canadian quarter as equivalent to an American one, and just stick it
in a roll with American quarters if it is turning in change at the
bank? Does the bank just leave it with the others, or does it get
sorted out at that point? Are the coin sizes and weights enough alike
to work in vending machines? Are equivalent coins which are really
different in value a problem in some areas, or not enough to matter?

This isn't numismatics, but it is about coins at least...
