Hey Wes;- About GOOD and POOR shells: I used to collect coins, pennies frinstance. Getting a MINT quality was usually out of the question. We kept our pennies in blue folders with holes in them for each date and mint. If we could only fill the hole with a lousy coin, it was considered (at least) a hole filler. We do the same thing with shells. If we can't come by a GEM Conus balonus, we can fill its place with a "hole filler" until a better one comes along. The only coins I still have in folders are English three pence silver pieces. Several are missing. Art
