As the title says, the pictures i took may not be with the right lighting or from the right angles, but if you read my dad's latest post, you will see I found a flat copper, nothing on it. I am almost 100% sure it is a coin and not a slug, because i've seen my fair share of slugs, and I don't believe this has the same.. design (can't think of the word, sorry). It is 27mm in diameter, give or take maybe a fraction of a millimeter. After doing a bit of research, i found a copper that size is a KG III Half Penny, and i would be STOKED if that is what this was. Thanks in advance for anyone with ideas, and if you want different pictures let me know, because I know these aren't very good. (One of them will have an outline, but that may just be from me TRYING to see something)
