I have a gold doubloon dime size & can't find any info about it - found some with some of the same markings?

If the item you have says doubloon on it then it is some type of modern token that is gold colored. The term doubloon is a slang word and was never used on the real coin. The Spanish American coin called an Escudo was dime sized up to 1800 and the 1/2 Escudo was that size after 1814 the first issue of that denomination. It would need to be seen by a coin dealer or two, or if there is a coin club in your area they would be glad to help. I would need to see scans of both sides. Hope this helps.
