You can find these coins by hand sorted enough pennies. Maybe one in 10,000 to 50,000 are like this? \r\n\r\n**Rare transitional wide/narrow “AM” USA pennies:**\r\n* 1982-1992 normally have a Wide AM\r\n* 1993-2008 normally have a Narrow AM\r\n\r\nSort out just the zincs with coin discriminator / Ryedale\r\nSort out memorials. This leaves you with 1982-2008 pennies\r\nManually sort some by decade. 82-89, 90-99, 00-08\r\nGet a model working that sorts heads by decade. So split 90-99 apart by memorials from the 80’s and 00’s. \r\nManually split some by 90-92 and 93-99\r\nGet a model working that splits the 90’s pennies in two: 90-92 and 93-99. This model should work on both side of the coins. \r\nBuild a model that work on just the memorial side. \r\nIt’s done, then look for narrow AM’s in the 90-92 pile and wide AM’s in the 93-99 and 00-08 piles. \r\n\r\n~~I have already built models that pulled out 1982 copper cents from machine sorted copper. It wasn't that accurate, maybe 80-90%, but did not not spend much time trying.~~  These models where over fit when I put them into practice. I will have to try again some other way with the 1000 or so 1982 pennies. I have. Maybe one will have to get the orientation of the coin first so you can crop just the date out?\r\n\r\nIf your interested and local to the Chicago Area I do need help with this."},"comment":{"url":"https://api.github.com/repos/GemHunt/CoinSorter/issues/comments/163340234","html_url":"https://github.com/GemHunt/CoinSorter/issues/20#issuecomment-163340234","issue_url":"https://api.github.com/repos/GemHunt/CoinSorter/issues/20","id":163340234,"user":{"login":"pkrush","id":13420310,"avatar_url":"https://avatars.githubusercontent.com/u/13420310?v=3","gravatar_id":"","url":"https://api.github.com/users/pkrush","html_url":"https://github.com/pkrush","followers_url":"https://api.github.com/users/pkrush/followers","following_url":"https://api.github.com/users/pkrush/following{/other_user}","gists_url":"https://api.github.com/users/pkrush/gists{/gist_id}","starred_url":"https://api.github.com/users/pkrush/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pkrush/subscriptions","organizations_url":"https://api.github.com/users/pkrush/orgs","repos_url":"https://api.github.com/users/pkrush/repos","events_url":"https://api.github.com/users/pkrush/events{/privacy}","received_events_url":"https://api.github.com/users/pkrush/received_events","type":"User","site_admin":false},"created_at":"2015-12-09T17:57:21Z","updated_at":"2015-12-09T17:57:21Z","body":"[Dates are done.](https://www.youtube.com/watch?v=mU1LRAQGpiU)\r\nMint marks need to be added to the image processing pipeline.
