Dolla Dolla Bills

[Troy Spiral (13)]

My mother and I have this unusual way of (very slowly) saving.  Which was her idea and she does the vast majority of it but I'm trying to help.   What she does is saves dollar bills with my dads first initial on them  (B).  They aren't worth anything its just sort of a game.   I try to trade people my 1 dollar bills for theirs if they have any.   Once we save 500 then we split the money which for me is ... a win since my mom puts WAYY more into it than I do.   Although its slow as hell.  My dad has been dead for several years and we started it like a year after he died.   Just now above 400. 

 

If you have any ones laying around and could take the time to look if you have any "B"s  that is the federal reserve seal of B (which means it was printed in NY) if you could set them aside and trade me at some point it would be appreciated.  

They look like this  (The letters range from A (Boston) to L (San Fran)  B is what we are after: 

 

 

Again I'm not trying to make any money these aren't worth any more than a dollar I'm just looking to trade 1 for 1.   If you know anyone that uses cash regularly if you could ask them too that would be helpful.  (That has been my problem so far I nor most other people I know don't use cash much.)  

If you go to the gathering that would be ideal but mailing 5 1 dollar bills costs 1 stamp which I can surely pay for.
