I just had a member of this forum send me a half dollar and he was charged $1.24 by the USPS. I sent him a PM that included the following.

I weighed your letter and it was .68 oz. I’m not sure where they come off charging you$1.24 in postage. My guess is that they didn’t like that the letter was not flat and they wanted to treat it as a package. Also, you covered it with tape. That was great for me but, the USPS doesn’t like things that won’t take their machine bar code.
Here is how I ship a single half dollar using just a 44 cent stamp. I put the half in a 2x2 cardboard flip with 3 staples. I take a flat head screw driver and make sure the staples are pressed down into the cardboard. I take a regular 8.5 x 11 sheet of paper and a legal size envelope. I tri fold the flipped half into the paper and place it into the envelope. Seal, address and stamp. Final weight is .855 oz. Goes through every time and I get great feedback. You can even staple the ends of the paper to keep the flipped coin from moving around.
This way the USPS won’t try to charge you for a package, odd size, or non-machine friendly.
