I know this might not be entirely answerable a question since i'm asking about Singapore notes only, but do ladder numbers fetch some of the highest premiums among the other fancy number types? What if I had a whole running series except 1 or 2 of them, and it happens that the true ladder number is missing, would that make the whole pile of notes worth nothing more than face? Also, do premiums depend on face value or how many notes of that denomination were printed? Sorry for the many questions but I've just gotten into notes as well
If I'm understanding the question correctly: Yes, a serial number like 12345678 would command a very strong premium. The surrounding seven-digit ladders, like 12345674, would carry *much* smaller premiums, but should still be worth more than face value. I'm not sure you could get significantly over face for the six-digit ladders like 12345639. Ladders on scarce denominations like $2's and $50's would probably sell for more than $1 ladders. But a perfect ladder is rare enough that it's going to be worth a lot on any denomination. Partial ladders on high-denomination notes might be hard to sell, since the face value would be large compared to the premium.
ok... gotta hate those who get an unfair advantage handling those bank notes fresh from the printing machine before anybody does. imagine the disappointment when you by luck receive one of those 123... ladder numbers and anticipate the one winning number.... only to find it missing. I was so close! by the way, Singapore notes only go up to 6 numbers, as far as i'm aware. never really paid attention to them until now.
well, i'm not complaining now though. by chance I received a bill with repeated numbers, like 552200. what exactly was this type of number called again? how does this type of fancy number fare compared to the ladder or radar types? incidentally I just realized that an old bank note that's on the way now has a radar number. what are the odds!? although I don't know if that'll fetch anything
