peter ullmanT213 Coupon cards were issued in 3 series...Type I, II, and III. Type I's are the toughest...and should be the most expensive...followed by Type III's (those w/overprints probably more expensive than type I's)...followed by Type II's...which are the most common and can be found cheaper than comparable t206's...usually.
For a multiplier...I'd guess...assuming a vg common at $40:
Type II 1x
Type III 4x
type I 6-7X
type III OP 8X
just my opinion!
