u/Own-Significance-173

Non-ferus, fairly heavy, 20p for size comparison. Found in North England.

Very worn, I know, just wandering if it is a Roman coin, size is 21.5mm.

21.5mm, not sure on weight as I don't have scales that small. Definitely non-ferrus.

Found in North England, I assume this is agriculture junk but it is a bit small to do much agriculture work. 5cm from left to right, definitely iron.
