Flokizomb Valued Member United States 81 Posts	Posted 04/23/2021 2:18 pm so I was looking up pricing for this Rev. Split Feeder Finger struck thru Dime, is this considered Small , medium, Or Large? I got this coin in a Binder I purchased from my LCS of Error coins. I'm Looking to sell it should I have it graded first or no? Report this Post to the Staff

mikediamond Pillar of the Community United States 2737 Posts	Posted 04/23/2021 2:27 pm This is a clamshell separation error in which the semi-detached clad layer was bent back and forth until it snapped off from metal fatigue. It's value is slight. Error coin writer and researcher. Report this Post to the Staff
MisterT Pillar of the Community United States 2003 Posts	Posted 04/23/2021 2:32 pm Very unusual indeed! To the best of my knowledge, here is the problem with TPG's and error coins. They can authenticate and add attribution to the type of error but they can't assign a value to it like they do for normal coin submissions. Certainly worthy of a 2x2 but I say why bother with the cost of TPG. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 04/23/2021 2:50 pm Thanks Mike. Most of the struck on feeder fingers I've seen are not the shape of the coin, but the shape of the feeder finger tip: Report this Post to the Staff
Flokizomb Valued Member United States 81 Posts	Posted 04/23/2021 3:41 pm i found these on Heritage auctions that resembled the dime planchet I have. with the weight and thin ness. that's why I believed it to be a feeder finger Dime. Report this Post to the Staff
fortcollins Pillar of the Community United States 3644 Posts	Posted 04/23/2021 7:42 pm @mikediamond, A couple questions, to help me learn here, if you are willing. IIRC, the early experiments with clad coins used explosive bonding, but for obvious reasons that was quickly switched to rolled bonding. Except for the early years, consistency of bonding pressure shouldn't be an issue. Would that make the likely causes of separation some kind of foreign matter or a substandard thickness of a layer? Would this, in a sense, be a type of lamination error? Am I anywhere near the ballpark? Thank you so much for your expertise and willingness to help the rest of us learn. You are appreciated!

mikediamond Pillar of the Community United States 2737 Posts	Posted 04/23/2021 7:47 pm While the presence of contaminants between clad and core strip is often blamed for clamshell separations and missing clad layers, only a small minority of such errors retain remnants of such contamination. That, of course, doesn't eliminate the possibility of some invisible contaminant like a thin layer of lubricant. In the end, we can only diagnose the end result. Clamshell separations and missing clad errors are not lamination errors, they are bonding errors. Error coin writer and researcher. Report this Post to the Staff

silviosi Pillar of the Community Canada 6244 Posts	Posted 04/23/2021 8:58 pm Nice very interesting coin. How get out of the Mint? I have no idea. You has a crack planchet detached coin combinate with other things. The upper red circle I will let the specialists to pronounce. The black line I done is it a request for you to tell me the dimension to tell you the % of missing. The bottom red circle it is the crack planchet. Very nice coin and I thing it is worth to certify with right request and good price in auction. Report this Post to the Staff
