Im new to the coin collecting world and i love it. Im trying to learn what im seeing. Hours of late night coin searching through a 15 gallon coin jar can confuse as much as excite me on this journey. I hope someone can help me to know what im seeing in these pics. Is this double die or just " worn out" coins? Im also including a 1966 coin for opinions on the " mint mark"... Or atleast a mark where i thought the mint mark would be located. Thank you all in advance for any education you may be able to enhance my eager to learn brain. Ive tried to load pics with the " mint mark" from a different angle
Lots of wear on the 1957 cent. There appears to be an obliterated MM on the other coin, however, since the 1966 cent was only minted in Philadelphia, a smooshed die chip must account for the mark.
Since you are learning, it is good to start with proper terminology. It is not double die - but "doubled die" or "hub doubling." And, welcome to CoinTalk @Dreamin_Sqaw !!
Just to be clear, mint marks were omitted for all US coins minted in 1965, 1966 and 1967. The Philadelphia, Denver and San Francisco facilities all minted coins that year, but there is no way to tell which facility struck your 1966 LMC. Source: Coin World Almanac. Eighth Edition. 2011. Page 267.
It appears to me to be "moved metal" on the 1966 under the date. A die chip would leave a lump on the coin and not a gouge. I think it is just PMD.
The very first pic if the 66 in the correct orientation appears to me as half gouge and half lump. The bottom half is the gouge, the top half is the metal lump that was moved out of the gouge. If that were an anomaly on the die it would likely be on hundreds or thousands of coins in the exact same place and exact shape.
I spy a raised section on both the upper and lower portion of the "irregularity". You see a gouge. Only the owner of the coin will be able to advise which thought is correct.
