I’ve seen sources which indicate where T213 Coupon Type 1 and T215 Red Cross Type 1 are considered in relation to scarcity of T206 backs, for example
http://www.t206.org/backs.php. I get that Type 1 is included because they are arguably T206 cards.
My question is where do you think T213 type 2 and 3 and T215 type 2 would fall in the T206 scarcity spectrum? I understand there isn’t a solid argument for these types being T206 cards, but just curious where they would fall in the scarcity range?
