This is the Japanese piece that I think @gxseries is referring to. This one is 1860-1869, Japan, 2-Shu. But it's not 75% gold. Just under 30% according to Numista. And very small - about 13mm x 7.5mm.
That's really neat, thank both of you guys for the info and posts!
Me either eddie. I'm pretty sure they're aren't any. If there are some out there somewhere, I think it's good bet they're gonna be modern.
That’s very interesting coming from you, Doug. I wonder then how a government would value a coin like that while on the gold standard, say. A coin like that would be a hybrid coin. Morgan, $1, Saint, $20, Hybrid, $10? Maybe from an economic standpoint it wasn’t feasible. Although, from a collector’s standpoint, I have to repeat, I want one!
Here's the thing eddie - as long as the gold fineness doesn't change they'd value it the same.
I think a lot of folks don't understand the difference between white gold and yellow gold. The only difference, the only thing that changes, is what the other alloy metal is. 22 karat yellow gold stays yellow because the other primary alloy metal is copper. But 22 karat white gold is white because the other primary alloy metal is silver. But both are 22 karat, or 20 karat, or 18 karat or whatever.
The defining thing you have to understand is that the gold fineness doesn't change between yellow gold and white gold. The fineness remains the same, only the color changes.
But then here's my thing, Doug. Silver is worth significantly more than copper. At the same weights of gold, the white gold coins should be worth significantly more than the yellow gold coins. White gold anything should be worth significantly more than yellow gold anything.
To complicate this some, I understand electrum is typically unearthed tainted with copper. But, as you say, its primary alloy is silver.
Yeah, silver is worth more than copper. And yeah, white gold is worth more than yellow gold because of that - just not much. Consider that most gold coins are .900 fine or higher, some considerably higher. So you end up with anywhere from 1.5 - 10% silver out of the total weight of the coin even if there are no other metals mixed in. And even if the gold coin weighs an ounce, and most don't, a tenth of an ounce of silver is worth what at today's prices - $2.50 ?
Not exactly a significant number even when you use the max possible. And it only goes down from there.
I agree. I wasn’t thinking, the less gold, the less valuable. In a white gold ratio of 50/50, that’s still probably less than a yellow gold ratio of 90/10. In coins of 90 gold, the difference in the alloys is less significant that I had it, that’s right.
Or this could all be wrong.
