bad stamps

What do you do when the first attempt at stamping a bill is unreadable.
Do you stamp it again
leave it go
try to remove the first stamp.

every so often one of my stamps come out unreadable. i am using a round stamp. usually i stamp the left side around the federal reserve seal, but if the stamp is unreadable I sometimes I restamp the right side. The thing I worry about is over marking bills

I wouldn't worry about it if I were you. Two stamps is no big deal especially if it is only on bills that don't take. Most likely this is the first bill you stamp out of a group right? Try stamping a piece of paper first to get the right ink coverage. Must be plenty of junk mail you can put to good use.

Well, I think the round FRB seal stamp is hard to line up and can lead to many a bad, unreadable stamp.

I like the rectangular stamp...you can stamp it just to the left of Washington, above the left-side serial number, and to the right of the FRB seal.
