Thanks Andy. Unfortunately, I don't see an F on any side. I should note that they have been drilled from the 2 through to the 4, as if for a keychain. On one die, there is a name, partially drilled through and the word dice lightly etched into the side.

I am also now noticing that them numbers do not match. On is 7283 and the other is 7286. Oh well. I don't intend to sell them.
