Here are some of my recent purchases from Auctionzip.com. There was a 15% Internet buyers premium. Shipping was $6 which was flat rate + insurance.
I just noticed something after posting this. The Eagles head on the 1878 is very different from the 1879 1878 $15

1879 $17.50

1935 $19

1974S $2.50 What is the film around the edge of the obverse? Any ideas?

I have some more, but need to retake the pics. I accidentally deleted them during transfer and resizing. You guys gotta check out Auctionzip.
