Hi guys, I just picked up this penny in a coin collection at a garage sale. It looks and feels like an off metal error. It's a bight lighter, the edges are white, and its got a silvery/gold finish to it. It also has extra metal on the reverse as seen in the pics which is indeed raised above the surface of the coin. The coin in question is on the left, the coin on the right is just a normal 1961 penny for comparison. If anyone can identify this for me that'd be great or any info at all would be nice. Thanks guys!!
Also, this is my first post here and I look forward to being a part of this community!
