1971 Washington Quarter Plated Or Acid Bath?

You can see extra material around the rim on both sides and in some letters. I would say plated.

I am going to throw this into the mix. A cast counterfeit.

I was hopeing someone was going to guess conterfeit. The coins texture looks like old lead fishing weights my grandfather use to make. Why counterfeit a 1971 quarter? What metal?

Many quarters were counterfeited. There are a fair number of them from the 1970s. many are cast from lead or other base metals.

When it cost about 3 cents plus time back then to make a bogus 25 cent piece, people actually made a profit if they could pass them.

This stuff still goes on if profit is involved. Did you know, for example that about 2 of every 100, 1 Pound coins circulating in Great Britain are fakes?

Have Fun,

Yeah... wheezy has it now. I'll tell him to take a better pic for you.

Wheezy is going to describe the rim from memory at the moment and I'll give it a try to get a picture later. I studied it when it arrived and I do recall the grooves on the edge actually appear to be incomplete and unevenly spaced. They almost look like somebody used a butter knife edge to make the grooves.
I have put this away in a hard 2x2 for now in a drawer next to the sleeping beauty upstairs right near the rolling pin she keeps handy. I already have a headache from the kids on the bus so I can't go get it now. I don't want to get konked on the head if I wake her up.
