That is quite probably true, and if you would keep an eye out for these, I would be eternally grateful and have to find you something nice in return.
I know down here, I can get all kinds of Mexican coins & currency if I move fast. Lots of collectors for that here. South American is also quite prevalent. Australian Pre-Dec is hard as the dickens to find locally, but I can usually get nice pieces in Houston. (3 hour drive, have friends we can abuse as a make-shift hotel.)
