T206 Piedmont Question
 

Are the 150 Subjects scarcer than the 350 Subjects ?

Any premiums attached ? I know the factory 42 subjects are the rarest of the bunch.

Do collectors have a preference ?

1- Yes, generally, 150 cards are slightly less plentiful. And they were distributed first, so subject to slightly more wear than 350, so top condition 150s are seen less often that top condition cards from 350 and 460.

2- Seldom does anyone note the difference, so hardly any premium.

3- I'd think generally, no.
