Alright... I can add to my Huggins post back there. Thank you, Chris. Now I have a Huggins T213 type 1.
I know the idea of thinking of the type 1 Coupon cards being like T206's crops up. In a slab they look similar. Hold one in your hand and it is obvious that the type one cards are virtually on paper, not cardstock. The type 1's aren't at all like T206's. At least the slim American Beauty cards look like they were T206 size until a side was trimmed. Their thinness, their fragility, would be a contributing factor to there being few of the type 1 cards...
