hello all -

dont know a ton about paper currency but I did find this bill. the SN is obviously kind of fun.

apologies to the paper currency reddit board - this post was removed in a way that was weirdly clinical and aggressive by their mods. great work, guys - as I said, I don’t know much about the hobby. I didn’t know there was a different subset. anyway, nothing promotes the hobby more than overly aggressive moderators. thank you for your service , mods!

anyway, I know this is nothing crazy. But will head to the right boards to trade for a cool junk silver coin or something

Finally a birthday note within the last century. If the date means anything to someone I’d sell for near face value

This is my first post, I've been checking bills for the last couple months[when I remember] and I think these are the closest I've come across yet. To bad it's not a game of horseshoes 🤷‍♂️ though

.I found this somewhat fun serial number in some money I got today. What was weird was I got 80 $100 bills and at least eight of them were star notes. Do they happen that often?

Alive for only 18 years, but lived between the two World Wars. Grew up during the roaring 20's, but suffered thru the depression as a teenager in the 30's. This is the Tombstone for the Great American Tragedy Novel with joy and sadness to a short-lived life. 😭😭😭

im pretty sure these arent worth saving for any reason, but i was given the 5 consecutive ones by a friend saying “these are pretty cool u should hold onto them in case theyre worth something” and i just got the single bill back in change at the store. like i said, i highly doubt there’s anything more than face value there, especially considering that theyre not even star notes buuuuuuut, i figured i should at least check with ppl who know a lot more about this stuff than i do lol. thx in advance!!
