I have thought that these coins needed to have denomination on them to be good, like “1 dol” or “1/2 dol.” The pieces with a bear or “Eureka” on the them were not good. Ditto for pieces that have only a fraction like “1/2” or “1/4.” If those pieces are good, I’ll pass.
Very few of those pieces that aren't denominated with 'dol', 'dollar' or otherwise to go with 1/2, 1/4, or 1; here's one that's not. BG-1328 is an 1864 brass dollar with a Liberty head; the reverse has '1' and '1864' under the 1. I've got one of these that I think might be genuine; it's holed and no better than AU details but it has a better chance of being genuine since it looks to be made of brass.
Check my work, then? One troy ounce is 31.1g. 0.31g is 1/100 of a troy ounce. So whatever the price of gold is per troy ounce, 0.31g of pure gold would be worth 1/100 of that. Today, that's about $33.18. Where am I missing a step?
Quoting myself for a reason; the first sentence in the above is a fragment. Generally most California gold coins with a BG number are denominated with 'd., dol, dollar, or likewise.
If it's gold, even if it's only 10k you should get between $250 to $350, personally I would keep it. I have a couple and I'm not looking to sell, I've sold quite a bit of gold here on CT but not these California fractionals, not today! Hard to get a decent pic but you get the idea!
Not my coin, it's a friends and they want to dump all of their mini-collection for cash. I think I'm stuck taking this to my guy at the LCS. I don't want it, I don't collect anything other than Lincoln cents and have been selling off stuff that doesn't fit for the past 20 years.
