I forgot to mention in the title: 1xRing included.

Both are Spanish issues from the 16th-early 17th centuries. Denomination and an accurate reference can be determined by the weight and diameter. This question is better suited to /r/coins than here, though.

These appear to be Spanish 8 Reale coins, circa 1658. This type of coins was also known as "pieces of eight." I'm not super confident on this identification as the coins are heavily marred and are pretty hard to identify without full details. I'm not an expert in coin identification by any stretch of the imagination, just someone who used to collect old coins.

This was the closest comparison coin I could find online. What I can read of the text seems to match up between the coin in your image and the comparison coins.
