The nickel on the left certainly looks like a type 1 to me, there's no mint mark, and the date is worn off. But it looks like it has a rotation error of about 30 degrees. I took the picture of the reverses first, then carefully flipped each coin as precisely as I could. The two nickels on the right match, while the one on the left is off. I don't know much about buffalo nickels, so I'm wondering if this is common or not.
