A bit off topic, but what’s her source for Eisenhower dollars? I discovered them by chance at a bank one day but haven’t been able to find them at another bank since, while $2 bills are in stock pretty regularly.
She is a money nerd and casual collector. Working as a teller in college, she was fascinated by unusual currency and bonds, etc. (As late as 1999 she would get old folks turning in WW2 era victory stamps/bond.)
Basically, when we go somewhere new, we look for bank branches or sometimes supermarkets that cater to old people and ask for weird coins. Depending on the bank, tellers sometimes end up carrying these in their drawers for weeks and are happy to unload them. Locally, they know her and sometimes save coins. You develop a sense for banks that are more productive for this -- a more modern bank have staff who don't know what nickels are! :)
Sometimes you get lucky. A few years ago, my wife and my son came back with about $200 of eisenhowers, including a few silver ones. They basically bought $1200 worth of coins for $200! Some kid/grandkid probably turned in grandmas stuff.
