I haven't found anything fancy or even cool in serial numbers recently. And believe me when I say I have been looking! I even ask my co-workers to show me their paper currency! This was in my change this morning. Nothing major. I think they call it a mixed ladder? All the numbers from 2 - 9.. Just missing the numbers 1 and 0.
I've been looking too and nothing for awhile so I figure I'm due for a hit soon. Hopefully you are as well. I noticed the numbers but to me it's a spender.
A recently found odd number note. Repeater with second # double of the first. What could you call this one?
The Deli next to the building I work at.. I sweep their sidewalk I get a roll with butter and a cup a coffee for $1.00 and sometimes for free!
