I was going through some pennies and I tossed this 1973 in a pile and it sounded weird, "ting'. so I weighed it and it weighs between 2.4 and 2.5 grams. could it be silver?   |

I can promise you it ain't silver. But has a solid shot a tapered planchet error.

The reverse from 10-12*k. The weakness, and apparent slight angle are a possiblility. Or it could be underweight. Doesn't look altered to me.

A tapered planchet would weigh less. Could we see pics of the edge from at least two angles next to a normal coin, please.

Good request Frog. That would probably solve the mystery.

My other suggestion would be to make sure your scale is properly calibrated.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Well it is copper,it doesn't show evidence of having been soaked in a corrosive (acid or base), shows no evidence of excessive wear or having had the surfaces ground down, but weighs significantly below spec. Does show weakness in the striking. Rolled thin planchet.

I would agree with rolled thin plan as well.

Thanks for the followup. I agree that it's a thin planchet. In Memory of Crazyb0 12-26-1951 to 7-27-2020

Underweight planchet? Yes. I do not recall the term 'tapered planchet', but by reasoning I will make an assumption: the planchet was cut from the very end of the rolled strip, but not quite enough from the end to result in a clipped planchet. Correct my assumption if I am wrong. ----------------------------------------------------------------------------------------------------------------------------------------------------- I have a 1965 British Penny which is thin (about 25% under weight, but fully struck up), for quite a different reason: It is a 'Mint Sport', and here is the reason for it's existence: In 1965, employees of Tower Hill Royal Mint in London were informed that their job location was to be transferred to Llanstrissant in Wales, due to the advent of the production of Decimal currency in a brand new minting facility. Almost all of the employees did not want to re locate, so they showed their anger with a protest. They deliberately made all kinds of gross error coins, and tossed them by the handful over the security fence outside the Mint, for passers by to pick them up. My Penny is one of those protest coins. |

You are correct, when the ingots get rolled out the ends of the strip are tapered over a distance of several inches. These tapered ends are supposed to be trimmed off. Sometimes it didn't happen and blanks were punched from these tapered regions.

Been organizing my Lincolns today and happened upon this one while rolling up some 1973 Philly coins... heard a strange "ping" and decided to weigh it...  Flip the coin over and it has the same weak spots on the reverse's design as the OP's coin...  Asides from the planchet being a little thin, it otherwise looks normal... pretty cool find! CRH Nickeloholic. 1,600,000 nickels searched in eight years! Have found FOUR complete Jefferson sets!
