When coins are listed in the auction catalogue, has the listed attribution
been "certified" by McCawley and Grellman or must one view the
coins prior to the auction and double check the attribution for
themselves to be sure the listing is correct?
Another question: because our club puts so much emphasis on maintaining
a line of ownership, I've often wondered why none (most, anyway) of the auction coins
come with their pedigree. Can anyone answer that?
