Hi everybody! Well I found this coin a week ago whilst detecting. When dug it was pretty discolored due to its submergence over a long period of time in waterlogged conditions. It weighs 0.9 grams and at its widest its 17mm, shortest width is 15mm, so not a trick of the camera, it really is a bit 'ovoid'! As you can see, the obverse is just about worn blank. All I did to it was leave it soaking overnight in a solution to dissolve the staining. If anyone can help identify it I'd be really grateful. Thanks in advance!
I'm no expert, but using Coinoscope (free download to smart phone) I came up with: ½ penny - Edward the VI https://en.numista.com/catalogue/pieces162456.html If that is correct, that would mean your coin was minted around 1551, which would certainly put it around the time the America's were being settled. Also, the metal is listed as "billion" which Wikipedia says: "Billon (/ˈbɪlən/) is an alloy of a precious metal (most commonly silver, but also gold) with a majority base metal content (such as copper). It is used chiefly for making coins, medals, and token coins." That is some find. Let us know what other information you find about it.
Judging from the mintmark '1' on the reverse & obverse 'E D G ROxxxSPINA', plus the weight - 7th issue AR halfgroat of Elizabeth I minted 1601-2.
