Did some research on foreign coins being produced at Denver mint during 1971 and the weight matches perfect. What's my next step? Opinions?   |

What do you mean? This just looks like a Denver LMC, nothing special. |

Huh interesting, sometimes cents weigh less because of a thinner planchet, maybe that's the case here. Someone else should get back to you and tell you what's going on with your coin.

Thank you.. Comparing it beside another 1971 D, seems as they are same thickness but that's by eye.

Weigh matches perfectly with what? There was no foreign coin struck in any of the US Mints in 1971 that had a weight of 2.85 grams. Closest two are Liberia 1 cent at 2.59 grams and Nepal 25 pice at 3 grams. Problems are the Liberia is the right compositions, but over a mm smaller, and the Nepal is coppernickel, silver colored. Then you have the problem that both were struck in San Francisco not Denver, and they are also proof only.
I think you have a numal cent struck on a planchet punched from strip that was rolled slightly thin.

You are correct about Libria cent weight, I was mistaken. Thank you

Struck on a rolled thin planchet.

More food for thought. Reminder foreign blanks or planchets generally have a predetermined weight we can reference. However when blanks meant for US coinage are punch from stock material meant for foreign coinage. The weight can vary up or down due to a difference in material and or thickness. We also see mix ups with US stock material some years. Requires a little arithmetic. https://www.coinworld.com/news/us-c...-wr.all.htmlThat said the only foreign coinage I find in production at the Denver mint in 1971 was minted for the Philippines. The composition of all four denominations minted do not seem to match the subject coin above. So stock material rolled a bit thin seems most logical in this case. Thanks, Doug. |

I agree with the thinned planchet issue. Note the rims? See how weak they are? The lack of metal to fill the die is the issue. It looks like this one is not tapered at one end, but over all is thin, light in weight, so not a full could happen because of the lack of metal.

In addition, overall the strike looks rather weak.
