I had a Palmer from the 70's and I took the foil out and replaced it with a $20 dollar bill. The little bit I cut out didn't affect the bill either. I cashed it at a bank with no problem.
When I sold the cue a couple of years ago, the buy inquired about the foil, which had my name on it, and I told him I would include the foil in the package when I shipped it.
The cue, by the way, sold for a lot more that I thought it might.
I had no reserve with a beginning price of around $50 or so and the thing sold for something over $1700.00 plus shipping if memory serves.
