I personally like to show unlisted unknown cards as much as I can. But I dont report them anymore since the crazy low price listed for the last 7 years on the Holland Ice Cream Peckinpaugh unique example card I found on eBay in the early years. It sold years ago for $3K in G/VG and is STILL listed at $2500 NRMT
If no one comes back showing me more examples, especially on net54, I know I have something fairly unique.
example.... 1959 Esslinger Beer HR Derby Aaron (dont own anymore, another board member has it now), but now know it is most likely unique, since Ive flashed it about 20+ times, and even offered to cut my price at the time in 1/2 if someone shows me a scan of another example.
Couple more...
1933 R340? Sport Kings Ruth Premium (at worst this is a R309-1 prototype)
ca.1941 Kroger Bread
(email for scans if interested)
anyone have any of these???? Still asking
