As stated, I do not collect gold coin so not familiar. I am looking for a small coin to have set on a pinky ring, Not looking to break the bank so let's say $500 and under. Not really going for price, more towards looks. Ty for any info. Would prefer older coin but once again looks will play a big part not purity. Pic is just for fun, Jimmy and Bob playing soccer in 1967 I believe. Looks like they smoked and about to lift off the earth? lol 
As far as small gold coins go, I would think the most popular are the US $1 one dollar gold coin and the Mexican dos pesos gold coin, both are approximately 13mm in diameter and I think they're weights are pretty close to being the same. Both are doable in a ring and personally I would ignore anything bigger as you wouldn't want to look ostentatious!
I hope these help you. Not for sale I have had these a while. $1.00 Dollar has my state flower on it. Magnolia. Hope this helps you
just askin' (if you don't know you ask) don't "they" make California gold tokens copys? and are they real gold or real brass covered in gold?. that might be his answer.
I think the most popular gold coin in men's rings tends to be the Indian Quarter Eagle. Both the design and the size of the coin suit that need very well.
If you really want a “pinky ring,” I think that the Type III Gold Dollar is the best. The Mexican two and two and a half peso coins might be the cheapest. The eagle on those coins is quite attractive.
Up to $500.00? That's not breaking the bank for you? I think anything above $300.00 would break my bank I submitted this gold 10KR to NGC once. It came back Details .. I should crack it out and make my own ring also! If I remember correctly I paid $120.00 for it.
All you gotta do is strap a little band on the bottom of the slab. Never have to take it out then. I'm sure some TPG would be happy to do it for you....for a price
I always thought the 1 gram gold bars would look nice set in a piece of jewelry without breaking the bank. there's also some small 1 gram foreign or coin rounds. If you were stuck to U.S. probably 1/10th oz., 5 dollar eagle. for around $275.00, there the old gold dollars also, they are like 1.67 grams or so but probably cost more than a 1/10th oz eagle..... still for myself I always come back to the PAMP 1 gram, set in a square ring. $85 or so, and the rest can be spent on the gold for the ring.
I've never been able to stand wearing watches or rings. I can't help but notice them all the time, fidget with them, and lose them because I'm constantly taking them off. I've never tried a pinky ring, but just the thought of having a big clunky ring on my pinky is nothing short of anxiety inducing!
I agree, I don't wear jewelry often at all or a watch, mostly because of how I live, and that I work with electricity... (I've seen some things) but in my neighborhood the poorer you look and less flash, the less likely to be targeted by someone. Show off something someone might want to take, and they might try you instead of just moving on.... but I've also never felt really comfortable wearing any of it either so it's only for dress up occasions.
Potentially. Stopped by the pawn shop near my employer yesterday for the first time in several months. They had a bunch of 1g Karatbars, in bundles of 5. $495 per bundle. Yeah, no -- the last time I bought Karatbars, it was from another branch of the same chain, they were marked at just over melt, and I used a promotion to get them for about half that.
A "pinky ring?" Didn't that go out in the 70s? To me, flashy pinky rings on men is ostentatious, but to each their own. Note: I am not, nor never have been a fashion policeman. LOL
