Oh, and don't be too obvious about this one, because I'm sure
it would creep people out if you were... I look in the till
when I go to a store and make a transaction. I have seen hand
rolled coins before in cash registers that just had that "look",
like it had been rolled a long time ago, or the wrapper was odd
looking. If you have a "feeling" about what you see that brief
moment the till is open, you can ask to buy it from the cashier.
I admit that I haven't found a fortune this way, but I have picked
up rolls that looked old that turned out to be just that. I have
got a few rolls of wheat pennies out of register sightings, old
nickels, and home rolled dimes with silver.
I also have made nice with cashiers before, in places that I frequented,
and eventually they were comfortable enough with me, that they would
save odd stuff for me.
Ike dollars, currency with 'other than green'
seals, or anything else that didn't look the same as the normal stuff.
This has been a VERY good source for me in the past.
