TaeKenDo Pillar of the Community Canada 737 Posts	Posted 05/27/2019 11:20 am @SPP-Ottawa - Are you saying that the rims should have been affected by a proper brockage whereas on this coin, the rim is flatened ? Because from the photos I`ve seen of dies, I get the impression (no pun intended), that there is a concave shoulder that never touches the rim when the die strikes and the collar is properly in place. Apologies for (amateurish) description - I am. ;) Edited by TaeKenDo 05/27/2019 11:21 am Report this Post to the Staff
SPP-Ottawa Moderator Canada 10460 Posts	Posted 05/27/2019 11:59 am Why not try a search with Heritage auction archives for double struck coins of all nature and study those auction photographs... there is tremendous pressure when striking a coin, and previously struck devices which fall into the fields (highest points of the dies) for the second strike, are almost obliterated entirely...

TaeKenDo Pillar of the Community Canada 737 Posts	Posted 05/27/2019 1:02 pm I have checked many, I have seen several, maybe need to see many more. I can visualize the process, I`m having trouble bringing it all together because I`m seeing things like : coin was flipped and then restruck, etc. Is it at all possible that the Obv. was struck, then the coin flipped and the reverse was struck ? I know that doesn`t explain the other side which was flattened...maybe by the next blank ? Report this Post to the Staff
SPP-Ottawa Moderator Canada 10460 Posts	Posted 05/27/2019 1:33 pm In your case, the coin was flattened by whatever it was resting on, as another coin was pressed into it - there is no collar die, and the rim was flattened equally.... (vise job). At the mint, there is either a ball cap, Rim Fin or cupping of the edges, due to the collar die. In absence of the collar die, there is no rim whatsoever... and the diameter of the coin can change, but the Type II rim can still be intact. Here are examples of coins I just had graded and certified, note how the second strike basically obliterates the devices from the first strike... there is that much pressure... only in the devices (deeper parts of the die) do you have some degree of preservation. https://www.PCGS.com/cert/37951190 https://www.PCGS.com/cert/37951201 Also,full brockages are generally formed when a capped die strikes a blank... not a coin already struck (the odds of a previously struck coin, being struck by a capped die, are almost astronomical... (Zonad has the only example I know of a full brockage on a struck coin, and it is a counter-brockage). It is much more common with indent strikes (overlapping coins in the striking chamber). This is a partial brockage on a struck coin... imagine the striking pressure, and then go back and look at your coin... https://www.PCGS.com/cert/37951200 "Discovery follows discovery, each both raising and answering questions, each ending a long search, and each providing the new instruments for a new search." -- J.
