Hi everyone, It actually looks like there's a little D on top of a normal D. Any chance this could be an RPM? Thanks, Chas.
No chance. Notice how the letter was reduced in size where it was struck, MD all the way. Is that on the numbers also?
No, look at the bottom of the letters in your date? It's doubled in the same direction as mintmark. They should not look the same and if the same it indicates movment of the die during striking, not the mint-mark punch which occurred before a coin was ever struck by this die.
I guess I read wrong a while back. No I'm not trying to be one of 'those' guys who will try to convince others, I'm still learning what to keep and what to discard. Also, I remember reading up that MD was flat and not curved, I'm reading the "Strike it Rich With Pocket Change", and am looking at the 1960-D large Date (CONECA RPM-049) and it looks a lot like the one I posted, what the difference?
I think you might be thinking of doubled dies prior to 1990. Since the MM was punched onto the existing die by hand, any hub doubling on the die would not effect the mint mark and thus you would never see a doubled mint mark that was caused by a doubled die. Again, prior to 1990 that is. However, mechanical types of doubling can show on any or all devices of the coin.
Thanks Jallen, Still confused though. Please be patient readers. So, let me get this straight to see if I understand; MD cannot happen on MM's before 1990?
MD, or mechanical doubling, can and does happen to mint marks of all years. True hub doubling would not effect a mint mark prior to 1990 because the mint marks were added to the dies after they had been hubbed. Notice on the 1969S doubled die how the date shows extremely strong doubling, but the mint mark was not affected: Mechanical doubling which happens during the actual striking of the planchet could cause doubling on both the date and the mint mark. Because of this, a mint mark that appears doubled along with the date or other devices can be a great tell-tale sign that it is mechanical doubling versus a true doubled die(prior to 1990). It does get confusing! Hopefully I explained it better this time. :high5:
No machine doubling can and does occur on any coin any time there is movement of the dies during striking scooting, flopping, pushing, pulling at, during or right after striking of a coin. What cannot happen is a true doubled die including the mintmark before the early 1990's. Doubled dies occured during hubbing, mintmarks are added after hubbing. Doubled dies can occure (see 1995-D DDO-003) on modern coinage because the hubbing takes place with the minmark already added to the master die, hubb or galvano. The minmark is now in place during hubbing of the die, it was not before and on your coin. Therefore we look at the movement of the "D" in this case and get a hint that it's machine type doubling we then try and find other design element moved in that same direction. We prove the mechnical doubling then by knowing that this happend during striking and not punching because it happen after the mint tech placed the mint-mark on that die. The doubling of your coin's mint-mark could not have happened during the punching phase because it happened during the strike, we have used our knowledge to prove it by finding other same movement of adjacent (close by) numbers or lettering that mimic rather than set apart the doubled appearence of the "D".
Good point. They are not mutually exclusive. Throw in some die-deterioration doubling as well, and you really start to get paranoid about what was added to your drink.
Ah, now I understand. What was confusing me most about this were the before and after 1990 comments. Got it. Thanks all.
The mm is a form of die deterioration, and not MD the second image is rounded but distorted,a clear indication od DDD,and ddd can just only happen on the MM, without the other elements involved,and that goe's for MD as well. JIM
LOL Bravo rockdude had me cracking up When in doubt do not get rid of the coin Package it, Store it, Study the coin and the aspect of the minting process where the question comes from. Stewart
So you can't have DD on the MM before 90, but you can have DDD on the MM with DD and MD. after 90 you cant have RPM MM, but you can have DD and DDD and MD, but only MD or DDD on the MM. I hope that simplified it a bit.
