Rare Unstruck Penny King George V Era Dates 1920 To 1936

perhaps it was a presentation piece for the obverse design or a one sided trial strike to see how effective the design would be on copper or something along those lines, if this is the case than that would explain the offers you were receiving. one sided trials like this are known but are usually on pieces of metal larger than the die.

not trying to raise hopes of something like this, just thinking out loud.

perhaps the way it was struck, without a collar right up against the edge of the die like usual there was no sharp rim but just the impression of the die.

Interesting coin! I am interested to even bring this up... however is it possible that the "blank" made it's way into the dies, and the obverse die was the only one. lets say that the reverse die was taken out. so in other words: blank reverse and struck obverse.

These are mine and they're real.
A blank is not a planchet until its rimmed. When it is struck the force of pressure pushes the coin tight to the collar, thus completing the standing up of the rim. Keep in mind copper is soft and malleable so the possibilities of how it could happen are plenty.

what kind of sheer "explosive" pressure is needed to press / strike a coin, like for example this 1967 cent?
I would think that there is a time factor also involved and it has to be fast to keep the metal soft.

thank you pennyman007 those coins impressive. I have a couple like them . I found going through penny rolls. I don't know if you collectors heard about the two dollar coin. that sold about 6 to 8 years ago that came out of the mint. I believe it was in a specimen set sealed in that plastic. a collector payed 100,000,00 dollars for that set . the two dollar coin was never struck on the obverse. so how did it get in that set. these things happen. like stamps never being perfed. quality control is there but it still happens. The penny I have is so different , then the issue ones but yet it was produced along the same lines just slightly different, SPP I think will help us all out have a great day and may you all find many rewarding coins

yes it is . I will take this coin to that show. there is a dealer that I have send him pics, he has a couple of collectors that are very interested in this coin. plus he knows the dealers from the show I went to with the coin. they wanted to buy it themselves. I thought I would hold on to it for a while longer but the time is getting right to sell it.

ok, for the missing die idea. slurs diagram has the complete hammer missing. put it like this. your mother made you a great sandwich, but she put cheese on it, which you hate. do you ditch the whole sandwich or pull off the cheese and save the sandwich?

in machinery, it would be way too expensive to replace the entire hammer each time a die wears, so the die must be replaceable at the end of the hammer. if the die is missing, what strikes the coin? can a die be installed upsidedown?

adam e, I would think the larger diameter of this would be an out of collar strike anyways, but dont know how large the surface the die sits on is? as for the reach, think die clash. although how thick are the dies? is that too much dead space?

im not saying I'm right, or have all the answers here, was just thinking out loud as to a possibility. only time will tell, just hate waiting till may.
