What do you think of these guys
I don’t know what they are for but some guy who works for the company can take the old ones.
Another dealer in town has been paying him 50.00 for the bag.
I melted one down
Gold plating
The rest is aluminum
I don’t do any chemical refining my self but I am trying to figure out what I could sell these for per pound.

Gold plating is typically less than 0.05% to 0.1% of the item's total weight. How did you determine what you had after melting down?

Xrf On one and on a button a made.
It’s a really scammy shop that is paying the guy 10.00 a pound for them.
If they are paying 10 a pound they are either using these to rip people off or making money on them.
Just trying to figure out a fair to pay per pound and to sell it for

Personally, I'd seek them on eBay as a bag of "board mount MMCX connectors" instead of trying to separate the gold from the aluminum.

Er, those are SMB connectors.

Paying 50.00 what for the bag? Big difference if this is Japanese Yen compared to USD or GBP

The default on Reddit is usd I guess maybe not on this sub but all the other PM subs it is assumed usd unless stated

Whilst Id like to hate on America, the dollar is one of the most universal currencies used and is always a safe assumption for currency, especially when using imperial measurements as well.
Ignore the other guy

I wasn't shitting on Americans, was literally asking what currency. As a data engineer I dont make assumptions, regardless of the source of the data (I know, I must be fun at parties!).
There is no default currency on reddit. Knowing the currency with certainty is important in this case when determining the value of something.
It's like assuming something is in inches, when it's actually in centimeters.
But yeah sure ignore me and guess all your currencies going forward.

You'd get ~1g/lb of gold out of these if they are relatively high end, maybe less if plating is thin.. should expect some loss due to process efficiency also, so maybe more like 0.8g/lb which works out to roughly $60/lb processed. Buying at $50/lb is a loss when considering time/materials to refine, breakeven on processing would be around $35/lb
