Would like to know the rarity and value of a mint error coin.

I came across a newer state quarter that is a blank planchette on one side. I have weighed it, has the same weight as a normal quarter, so it has not been milled. Any info would be much appreciated!

That looks like it was mechanically altered post mint. A true uniface strike would have a strongly finned rim on the blank side due to the extra striking pressure.

Incomplete planchets wanted, especially Lincoln Cents & type coins.

It's been machined - damaged.
It did not leave the Mint like that.

Does it stick to a magnet? And, which side is planned down? Makes a difference in value.
Non-magnetic, heads side of coin is stamped, also no edge reeding
Photos needed.
If it was struck with another blank at the same time it would be a rare uniface error and a great find. Please post a photo.
I would like to see a photo of it.
Thank you ALL for your interest and information !
The reverse looks unnatural for a uniface strike. Reeding looks "squished" with a lip on the edge. My bet is on post-mint damage. It looks as if the coin was placed in a ring and the reverse was pressed flat. The remnants of a rim still appear along the edge (which would not be present on a uniface strike).
Depending on the precision of the scale to measure the "equality" of the weight as compared with a standard quarter, a small amount of metal (raised devices) could have been removed to assist with the "uniface" appearance.

the reverse photo seems to show some remaining design details at the bottom. It appears to be part of Pennsylvania.
correct!

That would be PMD....not sure why it was done, but it was not an accident.... Cheers, RickO
