I found one of the same types about 30 years ago....in Petersburg, VA park. Think it was the same date, too.
Not sure if it is Spain, or what country. Found mine along with another older, foreign coin.....that I can't remember
anything about, except that I found it. Good find....older foreign coins must have been used as some sort of trade
material. They were here in S. KOrea.....all traded according to metal and weight.....Japan, Korean, Chinese, and I hve
heard of some Korean coins found in VietNam......wish i could find a Vietnamese coin here in S. KOrea.
Good hunting......
