...Well, sort of. I haven't picked up anything other than pennies in probably a year, but on a whim, I picked up a hundred dollars in halves from the bank. Here are the results:
A whole lot of nothing
2 40% Halves ('66 and '68 D)
3 90% Kennedys
1 Walking Liberty ('44)
If that isn't an incentive to pick more up I don't know what is. Now, I'm going back to get the other $50 she said she had, but couldn't give me.
