No, it's only worth $50. You'd be better off spending it. Edit: It's a partial reverse ladder, so it might be worth more than face value.
Interesting. I've never considered using two contiguous numbers as a two digit number. I've never even seen it mentioned. If it were mine I'd keep it and do some research about that. Unless setting aside $50 would put a crimp in your living.
The answer I received from the known dealer is, 'No, it's not a fancy number.' There are only four true ladders: 98765432, 87654321, 12345678, 23456789.
I might point out...my interpretation and not to be nit-picky...also if I see the numbers correctly...that you must use the second number in 11 (1) to make the first number in 10 (the same 1), so the reverse ladder is really from 10 down to 5 and not from 11...5. Would that be right if it means anything effecting value...? No paper expert.
Man, if it ain't worth nothing, just give it away or hide it. But don't put it under dirt, paddyman will find it. A little humor, thanks for the post.
Walmart is always a good place to spend it, like the others nothing special about it usually odd serial numbers make it valuable along with condition.
