I got this $10 in change and was wondering if the serial is fancy enough to keep. MF 12356890 D While it skips 4 and 7, it is counting and that’s where I saw the pattern. thanks
Just an almost. The numbers are all ascending, but I don't think it qualifies. You never know on Flea Bay.
I wouldn't post it as a ladder. Make up your own term, then you aren't lying. "All ascending serial number" or something.
01234567 12345678 23456789 34567890 (although 1-8 aesthetically the best) 09876543 98765432 87654321 76543210 I think these are all ladders. Going up or down in order, all 8 numbers.
