@Mallard4468 posted:I've never had a problem paying with a check at a TCA meet, but cash speaks more loudly. If I was selling, I'd beware of taking cash - there are too many counterfeit $100 bills floating around. I don't think that another TCA member (or the vast majority of train guys) would try to pass a bad bill, but some of them look good enough that a person could unwittingly have one. A marker for testing bills is a start, but not 100% foolproof.
If we knew how much cash was in the pockets of train show attendees, especially at major meets like York, I think we'd be astounded.
This used to be a much bigger problem than it is now.
Newer $100 notes, i.e. last 5 to 10 years, have many security features such as the thread woven into the paper/fabric that's easily seen when held up to a light, textured ink, holographic patterns in pictures and seals, etc.
The pen is only one of the methods to determine if a $100 bill is real.
