I found this in a farm field today. At first I thought it was trash but after cleaning it I saw what looked like a cross, and the overall shape/design made me think Spanish cob but I wasn't aware they could be this small. Can anyone confirm if that's actually what this is. Thanks
Cobs are clipped to weight at the mint.
If your coin exceeds 3.43 grams, it isn't a 1 R.
If your coin exceeds 1.72 grams, it isn't a 1/2 R.
The reverse of your coin appears to be part of a monogram (initials of the king)
Both Felipe and Carlos minted 1/2 R with their monogram on the reverse.
You might look in that direction.

Likely a Carlos II 1/2 Real that's been clipped, produced from 1665 โ 1700.
Buccaneers like Henry Every would have been very familiar with this kind of coin,
in fact I would bet yours once belonged to a pirate - for at least a little while anyway,
Assuming it's a Carlos II 1/2R from the Mexico City mint, we can tighten the date up a little more since that coin was only minted during the years 1668 through 1697; though his reign was between 1665 and 1700. The fineness was .931 silver. He was the last monarch of the Hapsburg dynasty.
