I found a small date 1982 Denver Mint 3 gram penny.

Just got this in change today it is worth more than 20 dollars to a collector

Given the overwhelming response to my previous post on curious $1 serial number bills sold, I figured I'd post another, sold yesterday.

"Bookends" are serial numbers where the last two or three digits are the same as the first.
Two-digit bookends aren't much to speak of unless there's something else going on.
Four-digit bookends are called "quad repeaters": the same four numbers repeat twice. Pretty sought after (I've got a couple for sale).
Three-digits ones can fetch a decent return of there's something unique.

This one is a set of four notes, uncirculated, all bookends, where the bookend numbers are sequential across the four notes (in this case 910, 911, 912, 913). Not something you find int he wild; gotta have few sequential stacks to pull them from (which is how I got them). This is one of those times where I get a bunch of BEP new stacks from the bank that at first glance are duds, no cool number sequence. On closer inspection I noticed the bookend on one, then realized that since I had four sequential stacks I'd have four bookends sequential too, and that's a nice find.

$9 for $4. Just over 2x, but now $5 earned.

Thought I'd start posting some of my sold notes to give people a sense of what's out there and values. I get a certain thrill from finding notes in the wild, recognizing their value and flipping them for a healthy return.

I sell several notes a week on eBay. Most of the notes I sell go for only a few bucks . (I've got a few recent ones I'll post that are more.) So while it's a thrill to get a 3x return just for keeping a sharp eye out on the cash flow, on a $1 note that's a grand total of $3 earned. It's not going to pay for retirement, but I get a kick out of it.

This one's an odd duck. The sum of all the serial number digits is 68 . Best you can do on a modern note is 89999999 with a sum of 71 and that one is going to sell for huge money because it's seven digits. This one's fun too because it's only three numbers used in the serial ("trinary"), they are 7,8,9 so "ladder"-like and for good measure begins and ends with "F" (the first one is the bank, the second is the print block). High sum notes are a bit of a niche, not nearly as popular as low sum notes (same idea, but low sum of all the digits).
