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.
My expert at my LCS confirmed it's gold. He said submit it, he agreed that it's in mint state. The plot thickens!
