Hi and welcome to CT. First, you need to save your images to a file in your PC etc. Then you need to crop them till all is left is the coin and save the changes. When you have composed your post, click the Upload a File button at the bottom and this takes you to your files. Choose your image(s) and upload to your post. Then, importantly, click on Choose Full Image for each image. When finished, click on the Post Reply button, and you are done. Good luck
@Rsred38 First, welcome to the neighborhood! Expat didn't "tag" you so I don't know if you read his reply about posting photos. You should follow his advice.
I sometimes use EDIT (Paint) to down size my pictures when I see 100% and I want smaller I type in 33% (or 50%) then choose JPG and it's Lots smaller. It works for me. Now to find a camera that doesn't do everything BUT take pictures. Things getting too complicated.
I have a 1982D small date and large date copper penny. 21 additional 1982 copper pennies. 1983 Lincoln cent with a spear going through Lincoln. I have never seen a quarter like this 2001 North Carolina? Where other than eBay can I sell my copper 1982 coins?
