What can I say there will be no end of this unless someone dumps it in an erupting volcano... Shameful and shameless consignor and dealers
It seems people have a very short memory and sellers count on it. The coin was brought in the market by Lanz and then passed through several auctions. CNG noted the tooling in their description and NOMOS withdrew it from their sale.
And as some people may not be convinced, here is the same coin with the tooling description by CNG https://cngcoins.com/Coin.aspx?CoinID=52764 and withdrawn from the NOMOS sale https://www.acsearch.info/search.html?id=4956240. Alan Walker announced before the auction that it withdrawn because it was extensively tooled.
