It appears to be a type 2. My eyes aren't what they used to be and it's kind of hard to see the mintmark.
If it is a type 2 proof, it's worth more than few bucks. Not talking cameo, the 81S type 2 proof SBA starts at around $100 for a PR60 and tops out at about $155 for a PR69. Cameo $120 to $165, and DCAM/UCAM(means the same thing just two different TPGs is all) about $130 to $800(PR70). Type 1 Type 2
I gave 5 bucks for it, which I thought was more than fair. It was marked $7 but he gave me a discount.
