I have only two 1910 COUPON cards and several T213-2's and 3's.
And, I don't agree with the comment that the Type 1's are of "thinner stock".
These cards were printed simultaneously with the regular 350 Series T206's in 1910. The two I have
compare exactly with any T206 thickness.
Hopefully RICHARD (rman444)....will chime in here and tell us if his Cobb is thinner than a normal T206 ?
Personally, my limited experience with these Type 1 COUPON's indicates that they were not printed on
thinner cardboard than a T206.
Can we get some more inputs on the question I have raised here regarding the T213-1 card's thickness ? ?
