Small Cross Coin

First off, to the community.

These two coins are very worn, so identifying them (mostly finding the date) can be very hard. But, I think the first one is a Spanish cob, and I think it could be Philip IV of Spain (so the date is probably around 1650). But I'm not really good at identifying these, so I could be wrong.

The second one seems to be also a cob because of the cross, but because the lack of detail, I can't really find a period (but it could also be Philip IV)

Anyway, you'll probably have to wait for a real Spanish cob expert to come help, but I hope this helped a bit.

I never support defacing coins, but since you found them that way you could do cool things with them. I was thinking earrings or charm bracelet fobs. Then you could tell people the story when someone comments on how cool they look!
