Hello. I recently have taken some interest in currency collecting, mainly
US coins and older bills. I come across tons of cash and quarters because of my job in the service industry and receive upwards of $400 in quarters per week. I have questions about some bills and coins I've encountered and wish to learn more about what I am coming across. I save as much old/rare looking money that I come across so I'll be posting some findings with questions. Hopefully I learn a bit. Thanks to all in advance
