Revised Post- 1806 Counterfeit Half Cent Update (un-deleted).
Sorry; I previously killed this post due to a concern I had already kind of beat this one into the ground. I have posted here and in a couple of other venues and lost track of what's what. The 1806 half cent fake was originally discussed in a thread here at https://forums.collectors.com/discussion/983930/relisted-scary-good-counterfeits-1793-wreath-cent-1806-half-cent and I had added a comment to that one previously.
I have updated the post; the Coin Week article can be found at https://coinweek.com/counterfeits/struck-counterfeit-coin-week-1806-c-1-half-cent-1-page-attribution-guide/
Since then I have had a friend report he has purchased the source example and another in my Dark Side group reported he has 3 examples, 2 raw and one in a slab; I hope to get together with both and compare examples and notes.
