First of all, it doesn't matter if it is 6FS if the condition isn't that good. Do you have better photos of both sides? Chris
It's in good shape for a circulation find, that's right. You'll not make anything on it, but it's a handsome fiver, and it's got steps, it's not like it's a solid blob, there. I'm keeping it, if I found it.
Yeah I also found a 1961 in great shape, that almost looks like a proof, it has a glossy finish on it instead of matte. The steps are more defined than this 56.
