You really need to see the reverse of the SAC to tell if it
is the pattern type. Just as it says in the article,
Quote:
it was determined that many of these coins had a prototype or pattern reverse, which differed from the final reverse design used for the circulation release
The article says "many" not all and from what I read, not all the cheerios dollars were the higher prices pattern.
The tail feathers are different on the pattern type.
I would not buy this coin with out seeing the reverse.
