One of the examples was my 1812 large cent counterfeit, a member of a "family" of fakes I wrote about in this forum and had an article published by Coin Week. Late Saturday a gentleman came by with 2 examples he asked I review; they were from a collection of coins he was assisting to sell and both had been marked as "electrotypes". He said he was showing them around to dealers there and suggested he bring them to me, but was told I just focused on counterfeits, not electros... Anyway, I was initially surprised by the surfaces of both, as there was light luster on both which my images don't show, but the surfaces were better than others I had seen. The next thing I noticed was the exact "beaded border" obverse appearance as all seen, and the "chip" in front of the face as well. Inspecting the edges there was no trace of a seam, but both were very squared off/ flat, and the rims sharp enough to practically shave with. So I showed and explained these elements and pulled my example from the case for comparison. He thanked me and said he had a couple of others he wanted to show them to, but came back later to take images of his and mine together. He then donated them to the growing teaching collection!
