1972 LMC under weight

1972 Lincoln cent with no wear and weight is 2.6 grams. Foreign planchet error?

Photos would be nice, so people can analyze the coin.

I am assuming this is a plain 1972 without a mintmark. 1972 was a troublesome year for the US Mint.

Place the subject coin on a flat surface, with another copper cent next to it. Do they look like they are the same height ?

Then take these coins, place them together and inspect the rim all the way around the coin. See if the coins show a pretty decent thickness.

The scale weight, I hope is using 2 decimal points, it is better for accuracy.

I will see if I can get to this later today. I have a copy of a 60-plus page listing of foreign coins minted in the US Mints. If it lists anything close, I will post it here.

Ok thanks. I used a caliper diameter and thickness almost spot on and weight is 2.61 to be exact. I tried downloading pictures but couldn't.

Photo uploads need to be less than 2mb each I believe and no more than 7 in any initial post, and I think each reply can have up to seven as well.

Nothing matched for year/ size/weight/mm etc in that 60+ page pdf. Admittedly, I did go pretty quickly thru the list, but I looked for 1972, 1971 and 1973 coins but nothing looked promising. I concentrated on planchet created in Philadelphia.

I will try and resize pictures and post nothing out of ordinary that's why I asked. Is there address to send to have looked at?

CONECA has a new way to handle varieties and errors. They pre-screen most coins, and if they decide it is worth seeing in hand, they will respond.

At the top of this page to the left is a FORUMS tab, click that and scroll down until you see CONECA SERVICES. One of those is for varieties, the other is for errors. Start a topic in there. It should be a private conversation between you and the CONECA staff members. Provide good photos, keep the glare down, by using some sheer cloth to diffuse the light. Explain with as much detail as you can about the coin.

Bob P. may have some additional guidance, he may wander in here.

Did pictures come through? So should I send to have looked at?

We really do need to see some sort of photo before you spend time and money to send it. Once that happens and we say you can send it in, then we have to have a CONECA examiner agree to see it and contact you with all the specifics. With underweight coins, being able to see a photo can exclude or eliminate many of the known reasons such as split or tapered planchets, acid or corrosive liquids, or other post mint damage.

Did they come through now?

[mustbebob]

They did make it through. Thank you very much for those. Based on those photos, and if your scale is indeed accurate, then it does need to be seen as it is about half a gram too light. Does the planchet seem tapered to you at all, or is it a uniform thickness throughout?

[JayBetAll]

No taper seems same all the way.

[JayBetAll]

So If I can get cost and where to ship I would love to have it looked at.

[mustbebob]

I do not know who the error examiner will be for this coin. I will attempt to find out for you.

Much appreciated.
