I posted a reply but it seemed to disappear. Anyhow, Baddog is correct it is 1923 not 1928. Thank you. I looked at it closer with a magnifying glass. I was fooled at first.
Wow what a super find! Congratulations!!! Out of all of those IKES, did you find any with an S mint mark? I'm thinking there might be a few silver ones in there. I can't imagine buying a 1000 IKES, LOL WOW!!!
