i Have looked this up and I can't figure out if this an error coin it weighs 26.9g and in the picture its clearly thicker than the other Peace dollar I have. can someone with more knowledge on this coin help me to know what I have
Which one is thicker, left or right? The thicker or thinner one may be counterfeit. That's what they do to make the weight close to correct depending on what it's made of.
Some collectors use a ping tester. I have one. They are not expensive. Wonder how much different the thick one would sound. A ping tester is only one of several ways to test some coins. I use mine on bullion coins and circulated Morgan/Peace but would not use it on valuable collectible coins.
The video shows how different metals ping at different frequencies and you can hear the different tonal note sounds. There are other YouTube videos about the pocket pinger for those who want to watch. It's not precise, can't tell slight differences in metals content, obviously not as good a tool as an XRF. But it's a good inexpensive way to test initially and then use other test methods. It's very obvious the sound difference between a genuine Morgan/Peace dollar and cheaper metals core fakes.
It's pretty easy to just use your ears to tell silver from not silver, or copper cents from zinc. But as you said, I wouldn't do anything to a collectible coin that involves making them emit a sound. According to Numista the Peace dollar dimensions are 38.1mm diameter and 2.4mm thickness. If you have a mm ruler it should be pretty easy to tell which one is closer to 2.4mm. I actually think the thinner coin edge looks more suspicious than the thick one - there seems to be a lip of excess metal.
The one on the right (first picture) seems to have a funky R and S in TRVST...? The R and T in LIBERTY look off...? The designer's initials look small...? idk? Keep us posted. smat
