Bicentennial Planchet/weight error

[Mouse0822]

I have a 1976P (no mint) Bicentennial Quarter that weighs 6.0g. I have tirelessly searched for similar errors and have come up completely empty handed. I know that even the 40% silver clad weighs 5.75g. I have even looked for possible planchet errors, but the US has no coinage that weighs 6.0g to my knowledge. I have attached photos. All attempts at MP4 video attachments have failed.
Thank you all in advance for your input, knowledge and help.

I doubt your going to be able to upload MP4 here, CONECA limits file sizes to 2mb. They probably don't allow video of any type. During an upload attempt, it probably throws an error/warning of file size and types.

In my opinion, Washing Quarters from 1965 to 1998 are supposed to weigh between 5.443 and 5.897 grams. From what I can see of the coin in the photos, it looks like a "normal" quarter. It isn't missing any devices, looks round and centered.

If you have a weak magnet, you may want to see if it sticks to it. If it does not, then it eliminates electroplating with a ferrous metal or possible foreign magnetic planchet. You may want to place a thick piece of cloth or plastic between the coin and the magnet so it does damage the coin.

In reality, the coin is 0.103 grams off. This could easily be just a slightly overweight planchet.

Planchet creation is much like rolling dough, some places might me a tad be thicker than others. Its not an exact science, and they try to stay within tolerances. It would be way too time consuming and super expensive for the US Mint to be exact. Plus we are talking about technology from almost 50 years ago.

Gary i tested against magnetism. And it is Nonmagnetic. Can this be considered a new find or mint error since it is outside of the tolerance level. Although minimal is that not why we have tolerance levels and MINT Errors? If not for the wide scope of oddities in our coinage why else do we have these forums and organizations?

In my opinion, its not considered a new find. Each error coin is slightly unique and this potential underweight planchet is pretty common. Its not a discovery piece by any stretch of the imagination.

Were talking about breaking this coin into 60 individual pieces at this point. Adding that much weight to one coin seems very minor to me.

You also should realize that its been many decades since true major errors and varieties have escaped the mint at a higher rate. Since 2002, the quality assurance and quality control have increased and the true major errors and varieties are becoming scarce.

People are then left with slim pickings if roll or bag hunting. People are occasionally finding die chips, die cracks and a struck through. They would have been estatic if they were collecting in the 1970s and 1980s or so since there were a decent amount of errors out there, especially from bagged coinage.

Sure your coin is potentially an error but collector interest in a coin thats 0.103 grams off will probably be minimal, especially from seasoned/veteran collectors.

There are legitimate auction houses out there (imo, ebay is not one of them) that offer some impressive error coins. The error-ref.com website also tailors to the error collectors educational side.

Forum are here to help educate and answer peoples questions. I will leave it at that.

My next suggestion is to make sure the scale is accuate / calibrated.

The relaxation of coin collecting is where its at for some collectors. It allows them to focus on something that may end up rewarding them if the conditions are right. Although scarce, there are some errors and varieties out there waiting to be found. It all depends on location, timing, luck of the draw, and type of approach, whether roll searching, bag searching, buying rolls of uncirculated coins trying to find varieties or outright purchasing of an error.

That is all I have in opinions for this coin.

Happy hunting.
