Ebay Purchase Dilemma (Special Mint Sets)

I made 2 different Buy it now purchases on Ebay. One was for a mint sealed box of 10 1966 SMS, the other a mint sealed box of 10 1967 SMS. They were $89.99 each, both from the same seller. When they arrived today, the package contained 2 boxes of 1966 (no 1967). I know of 2 varieties of Kennedy halves found in the 1966 SMS sets (A DDO & No FG). Anybody know of any varieties found in 1967 SMS (which might persuade me to return a 1966 and get the 1967 assuming seller still has it). I know I paid a good price because the next boxes he sold went quickly at $139.99, so I'll end up keeping these anyhow if he's out of 1967's.
