With an N# 17765 this coin must have been in the catalog since 2010 time frame (pre-exonumia days) so it had to have been migrated over after the exonumia catalog was created. If you sent a new coin request it would have been for one that already existed. Note that all the other ones in the catalog have a Type of "Token" so as
seltsamesammler implies the other ones may eventually end up in the exonumia catalog.
