Color numbers are:

4,5,6
9.10.11,12,13,14,15,16,17
19,20,21,22,23,24,25,26
28
30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50

Can you make a list of your numbers?

In my set, numbers:

1,2,3,7,8,18,27,29

are skipped. These numbers are also skipped in the set of small round color chips on a chain, so I have assumed that these original numbers in a sequence of 50 colors were dropped by Bud Jones at some point.

It would be nice to know the color numbers in different collectors' sets and which are skipped in the sequence from 1 to 50. I've had my set for 10-15 years but it could have been an older set when I got it. I can't see that there are dates on any of the pieces. I think both the puzzle set and the color chip set are pretty scarce.

My set of 42 small round color chips are shown in TheChipGuide as CG165528.
