By FAR, the folks over at ARA are the
best. After doing a ton of research, getting many referrals & reading countless posts, I settled on them. I got roughly 96% of spot
Here's a little tip

I sent my batch of gold return receipt through the U.S.P.S. I'd advise anyone else to do the same. On the day that the shipment is confirmed delivered, keep an eye on the price of gold. ARA gives you the option of 'locking in' your batch whenever you wish. So, as long as you know the EXACT weight of your gold, call them up anytime to lock in the price. They MUST pay you 98% as this is what they advertise. Again though, depends what the price of yellow is when you lock it in. B-U-T...
All gold - with the exception of pure 24k - is usually mixed with other metals to increase the strength of the gold itself. The lower the kt. the more 'other' metal is mixed in. ARA does NOT pay for this material...only the gold itself. Here's a little blurb I copied directly from their website;
"Q. How do we survive on 2% profit?
A. Low overhead, and we are a family-owned business that is not in it to get rich; instead, we do this for the joy of working for ourselves and with family, doing what we love and with pride for our company.
A. All Karated Gold contains some silver in the alloy; therefore, we do NOT pay on silver in Karat Gold Material.
A. Resale of Gold"
Clearly stated in answer (2). So, while they claim 98% of spot, one must allow for this added charge on anything other than 24k.
