I found this coin and thought it was pretty cool. it weighs the same as a silver quarter would weigh but is past the minting years when quarters were stamped on silver. I believe it was printed in Philadelphia as there is no letter marking for place of printing. I took it to a local coin collector in my area and he said it was rare. Does anyone have insight/history/known value into this coin? Please give your honest thoughts and/or guidance. (btw, I am new at this and so please give me lots of patience and understanding regarding response time).

So I have 1982-D Penny weighs
3.14 g which I believe is the copper to have the small date????? it is circulating, but if anyone wants to buy it and if this is the right one, lmk.

I received this 1945 walking Liberty half dollar recently, preceded to flip it over and saw this insane pattern on the back. It looks like a topographical map. Under microscope it looks like it's made of a bunch of small dots, somewhat inconsistent in many areas. But also if this was done intentionally it looks like it was done quite a long time ago since some of the lines are definitely worn away from circulation. In one of the pictures in the field you can see what might be a logo or something? I'm really not sure what this is! Any info would be appreciated, Thank you!

Silver and both copper exhibit diamagnetic properties. Using strong neodymium magnets is another tool to distinguish silver and copper from steel and non ferrous alloys used in counterfeits.

Not a perfect sleuthing tool, just a good test to rule out non ferrous and ferrous fake silver. Slide test reveal slight hangups for clads with copper, and delayed slide on .999 silver

Clads hang up slightly on slide tests due to copper content. Penny has little so drops a lot faster

Tested in order:

2025 copper-plated aluminum Lincoln

2018 Jefferson nickle*

2024 Roosevelt dime

1967 Washington Quarter

1776-2026 Liberty Half Dollar

(*No copper in the nickle, doesn’t hang up.) Non ferrous alloy category.

OPM 1 oz silver bar .999 Ag

Counterfeit Sunshine Mint 1 oz bar

Silver plated steel. Very nice counterfeit.

Is it possible for it to be washed without damaging it? I know it most likely holds no value other than face value. I just want to collect it not sell it so It’s in bad shape. Or you guys think I should just leave it as is?

I think it's a work out S for San Francisco. Small possibility it could be an O? Anyone able to confirm? I know it's not the best quality, but I like it :). I also was not the one who tried to clean it. I got it years ago and it's been in its bag\case since then, except for today when I wanted to check it out under the microscope.

I've heard knowledgeable coin enthusiasts refer to some of these coins with "enhanced hair". My question is, does my coin have the enhanced hair and if so, does it make it any better than one without ?

So I was looking through a pile of pennies I got, and noticed the 1968 s (first clip) has “in God we trust touching the top edge, top part edge seems like it thicker a little and the L In liberty touching edge, 1960 (second clip) had the L in liberty like closer to the edge, and last the 1974 (third clip) looks off centered.

Husband has been given a few coins of his great grand fathers, and this was sandwiched between a few other Indian cents. This is the only one with this kind of text across the front? We’re super curious as to what this is and can’t find any answers online
