USA gold market
In the US, gold prices are quoted per troy ounce in USD, with the COMEX (CME Group) GC futures contract setting the global reference. There is no federal VAT, but state-level sales tax may apply to bullion purchases below $1,000–$2,000 (varies by state — Texas, Florida and many others fully exempt investment-grade gold). Major retail bullion dealers (APMEX, JM Bullion, Money Metals) price coins and bars at spot + a 2–5% premium.
