Collecting Fancy Serial Numbers on Currency ... Birthday notes.

Collecting fancy serial numbers can be fun. One niche of this interesting hobby is to collect birthday notes. That is serial numbers that are a birthday. Generally people collect the following formats MMDDYYYY, or European style DDMMYYYY, or even YYYYMMDD or YYYYDDMM. Others even try to stretch this idea with examples like 01955113 (XYYYYMDD) or (XYYYYMMD). I still think the first two that I listed are the only real true ones.

There is even a subreddit called ''birthday notes''

Find your birthday on money.

https://www.reddit.com/r/BirthdayNotes/

The guy who runs the exchange has you send him a note when they find your note. That way it is free of charge. You can also look on Ebay and have a saved search that will allow you to be notified if your serial number shows up.

Have fun collecting.
