Hey Everybody, I found a Bicentennial Half Dollar struck on what appears to be quarter stock. It is not quarter size... it is a hair undersized from the half dollar, but very circulated. Trying to decide on best route for this coin. Is it worth getting it graded? Any estimations on possible value? Not the best photo's but it's the weight that's important... this comes in at 8.7 grams. edge is reeded just like regular half dollar Tell me what you think! Okay, I took a few pictures that are more clear...       Edited by Dennis omara 06/24/2020 07:58 am

If it was struck on a quarter it would be bigger than a quarter and weigh only around 6 grams.

A half dollar on quarter stock would weigh about 8.8 grams.
But judging by the mushy details and discoloration I think this is likely environmental damage, possibly acid treated, not a mint error.

Quote: A half dollar on quarter stock would weigh about 8.8 grams. A US clad quarter weighs approximately 5.67 grams. A half dollar struck on quarter stock would also weigh about 5.67 grams.

A half dollar struck on a quarter BLANK would weigh 5.6 grams. The OP has a half dollar on a half dollar blank punched from quarter STOCK. This would weigh between 5.6 grams and 11.3.

Ok, the OP has changed the post. originally is said... Quote: It is not quarter size... it is a hair undersized but very circulated. Which led me to think it was smaller than a quarter.

Half dollare on quarter stock will weigh about 7.15 grams. With tolerances figured in, between 6.86 grams and 7.44 grams. So we need a weight. But I agree it looks like environmental damages. If a half dollar planchet was punched from quarter stock and then struck, it would be the SAME diameter as a normal half dollar. And the fact that this undersized coin shows full reeding proves that at one time it was the full diameter. If it wasn't it wouldn't have pressed into the collar and wouldn't be reeded.

Not saying it not, but I would expect the details to be mushier due to the thinner planchet.

Arguing over the weight when there are other indicators (size, appearance) that this coin was not struck on the wrong stock. This is PMD, plain and simple.

Looks counterfeit or acid damaged to me.
Weight?

This was an interesting thread for me to read through. Thx to @do for posting this coin and the tanman for that comparison.

I agree with Spence and thank you Tanman for the link. If we look at the article (Numismatic News, Jan. 2009) the Half dollar on Quarter stock was a "...1971-D struck on a planchet of quarter-dollar thickness or what is called a "Wrong Stock" error. It weighs 8.8 grams versus the normal 11.34 grams for a clad half." This 1976 seems out of the norm but within reason for the time period when the wrong stock planchets were most common. As far as the weakness of the strike, maybe it's acid-treated, but the weight is reduced by 23%. And that would be coming from the outside layers of the coin if treated in acid. I would think some of the copper core would be visible. Congrats to the OP for realizing they might have something. I know I wouldn't have.

First, I want to thank everyone for their input, I am new to collecting and the information and questions you are raising are helpful in many ways. Now as for the coin: I do not think it was acid treated for the reason Petespocket55 brings up, the copper edge of the coin appears to be undamaged. If the coin was submerged or washed in acid enough to deplete the weight by at least 2.5 grams there would be clear damage to the reeding of the coin. Also the coin is not pitted nor is it an "uneven" diameter. I would think that an acid wash would deteriorate the coin in a disproportionate manner, making the circumference of the coin off. So I did a little research and found that the Philadelphia mint pounds out way more than just US coins, in 1976 they produced coins for at least 10 different countries. 1 of the coins comes "close" to what I have... it is the Liberian 50 cent coin, it has a diameter of 28.5 mm and a weight of 8.9 grams. it to was copper nickel clad. I figure this is the closest to the coin in my possession do to weight and the different diameter. by no means am I positive on this, but it gives me a better starting point... Thanks again and special thanks to Tanman for providing links!
