I was happy to find this today while looking around my stock. Its a 1987 S PROOF CENT. As of right now I only had time to put this picture together. Theres a strang tonning on the penny that lead me to think its grease or polish that coused this Double Bie. I will try and get some time to put up a few more pictues of any other errors i find on this coin. ANyoe seen this on a 87s penny? You can see the tiny trace DD on around the L & B as well the I of LIBERTY Anyone think i should send it to a TPGS ?
no gunk? its a proof coin. still in the us mint holder. where do you see green gunk? lol Actaully dos this look more like a clashed die then double die?
I don't think that it is a doubled die. Most likely a refraction from the copper plating being too thin and then with the strike the undercoating shows..
I looks like very a strong spread of Machine or Strike Doubling which not only pinched (smashed) off a portion of the Primary Strike but also created the breaks in the Copper plating and thus exposing the Zinc core. It has to be one of the strongest examples of Machine Doubling that I have ever seen as it appears to have Split Serifs which you would normally see in true Doubled Dies! The Other, Other Frank
It may simply be a case of split copper plating. I see no convincing evidence of machine doubling, "flat field doubling", or a doubled die.
Mike, If you copy and paste the picture of "IN GOD" and the picture of "WE" into an email when using AOL then right click on the picture and click on "Edit Picture", you can then blow the picture up. When zoomed to 100% or higher, you can see that there is doubling of the letters to the North Northeast of the Primary Strike. Since the Primary Strike lettering appears to be thinner than normal towards the doubling, then I am strongly leaning towards Machine or Strike Doubling. The Other, Other Frank
So the out come of this question is? What should I mark it as, when I or if I get it Slabbed? also ,, thank you guys very much for your thoughts on this one? If you guys have any proof sets from the 80's and early 90's id say look them over again. becuase i have found seven other proof sets from the purple case era with more errors like this but not the SAME in the pennys. Like zinc showing and some other spots with duobling, i will post pics of them when i get time, to share with you gutys and girls. Natesdad
Nathan: It is strike doubling. However, realize that it will not add any value to the coin. Strike doubling happens when the die (usually the top one) slips as the coin is struck. It is not a valuable error, and some feel, actually detracts from the value of the coins. So, perhaps -- save your money?!?
Natesdad, Treashunt is correct! The coin has Strike Doubling which will probably not boost the value of the coin even if it is Slabbed! Besides, due to the damage to the Copper Plating and the Orange peel look to the coin, it will more than likely grade fairly low in the PF category. The cost of slabbing it will be about three times what the coin is worth (unless you use the Economy Service and submit 10 or more coins at the same time). The Other, Other Frank
Nathan: Look at your photo carefuly, and you will see that the missing copper is in the same direction as the 'doubling' this is a sure sign of 'scraping' of the die as it moved. Therefore, strike doubling. Save your money, don't get it slabbed. Buy another coin with the funds instead.
Where do you see missing copper? The glare from the lighting makes it look like zinc. Is that what you think is scraped?
yes, exactly. Look at the 'blue' part of the inside of the lettering for G-O-D. That is probably (notice how I/we hedge all statements) the under zinc.
Im getting confused. I assumed everyone would have taken into consideration of the lighting. They is no zinc showing or zinc color showing. Its all copper color in real life. Sorry I guess I should have stated that the first time I posted the PICS. edit to add. LMAO. Yeesh I just wanted to add, that if I saw ZINC showing from under the top layer of copper I WOULD KNOW that is was zinc. I don't have very good lighting for my microscope. I pretty much have to deal with day light threw a window and a flash light. until I rig something to give me proper lighting from above the item im trying to see under the microscope. Sorry guys, again I just assumed you would have all known about the glare factor. AGAIN what ever look white or blue in those PICS is just glare. THE WHOLE COIN SHOWS NO SIGN AT ALL OF ZINC COLOR, JUST COPPER ALL OVER.
