Achilles Valued Member United States 60 Posts	Posted 07/31/2018 08:05 am Hi All, I found this recently in some change and was wondering if anybody would be able to shed some light on it. I believe it is a thin planchet error. A 'Split Planchet' would be choppy on one side - is this correct? I cannot find any other instances of a 1972-P online. It weighs 2.41 grams!

However, if the planchet lacked that much mass, would you expect that somewhere in the strike, the metal cannot fill? I am not intimate with this type of error. Report this Post to the Staff
Achilles Valued Member United States 60 Posts	Posted 07/31/2018 08:48 am From what I've seen, other instances of thin planchet cents have that hourglass deletion on the reverse. I think it's because there just isn't enough metal to get a full strike and the reverse area suffers most for it. It really is super thin, you can easily feel it when you pick it up. The weight is off even for a zincoln. What I'm trying to gauge is the rarity of the error for the date/mint and if 'Thin Planchet' would be the correct error name. Thanks for any information anyone out there may have. Report this Post to the Staff

Halo1st Pillar of the Community United States 2775 Posts	Posted 07/31/2018 10:20 am I'm thinking rolled thin planchet or stock. The weakness opposite the bust on the reverse is usually present, because of the material shortage, but also the bust seems to take up the resources before the backside can backfill fully even on planchets of normal weight . I don't see any roughness associated with a split planchet before strike. Though I've seen some websites list these as such. Another possibility is struck on a foreign planchet or rolled stock. I would need to research more to rule that out. Thanks, Doug. Adding: I see Denver and San Francisco were busy producing foreign coinage this year with a similar composition, but nothing listed for the Philly mint.

Achilles Valued Member United States 60 Posts	Posted 07/31/2018 11:24 am Really appreciate the feedback and the leads. I'm not familiar with methods of determining if a coin is minted on a foreign planchet but I did test it with a magnet - it's not magnetic and appears to be copper anyway. Will have to look into that, its prob not the case from what you're saying but now you have me curious. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 74846 Posts	Posted 07/31/2018 1:02 pm It's definitely a thin planchet issue. It only weights 2.41 grams. It's a underweight planchet. Errers and Varietys. Report this Post to the Staff
