Nice find! Now all you need are a few Cheerio Sacagawea dollars to go with those Lincolns for ten bucks! Lol
There is a die marker on the obverse Lapel that will identify them as a WAM. I will see if I can find the link. Wait that might be for the Accented tail feather reverse on the SAC. I will take a look. Yes it was the Small dollar. Sacagawea Dollar Pattern/Cheerios Dollar (smalldollars.com)
How much was the shipping? Be honest now Nice score though, I still have trouble with the 10,000,000 mintage figures.
