Future values of the "AP" will be split into two groups.

1. Paint Samples,true artist proofs, as John Mentioned above. This group will have the best potential to retain greater than retail value.

2. Non-paint sample AP's.These are sales samples. I doubt that lower numbers in this group will contribute to a higher value over time as many of these are the same as regular production with different labeling. However, some toy sales sample kits from the 20,s' , 30's , 40's etc. sell on the antique market for a fortune

Just my opinion
