Thanks Spanner, fair point.
I'm not a note collector at all. I literally stumbled on these.
I figured they're cool even if imperfect.
They came out of a ball of wool where they had been rolled up for probably 30 years, I didn't even try to flatten them out before posting them.
Rather than banking them I think I'll keep them and use them to pay for things.
Just looking through them now, I notice there is one in the stack that has smudged ink on the middle 0 in the 100 on the Tedbutt side.
