1979-D SBA Dollar
Mated Pair Struck Together
This is one of 2 known mated pairs of SBA Dollars. They fit perfectly together and are tight and snug and lock together in place.
The first coin has a major indent since the second blank was resting on top of it when these were struck together. The second coin was struck off-center over the first blank creating a uniface reverse. A spectacular and rare mated pair of SBA Dollar mint errors.
