And why would that be? I sure don´t know, but now I have some time to find out. Gold jewelry is easy to buy (at reputable shops even), but I have not "found the key" to find bullion coins or similar. The couple of times I briefly looked for gold coins were Peruvian ones that circulated (at least some) decades ago, but the mark-up was around 40%, yow!
Peru does not produce bullion coins even though they are No. 6 in world gold production. THAT might make a nice little item for them to make, maybe at a slight premium...!

Another possibility might be to buy local gold in bar form.
I once in another US city was buying a gold coin when a guy entered who needed a few grams for his jeweler employer. The shop did not have gold shot or other 24 kt around, so he opened up a 1 oz gold bar container and melted off the amount that his customer needed. I did not find out how much nor what the mark-up was (but I imagine it was kind of steep).
I do know that PLENTY of jewelry is made here (and the work is cheap), but I do not know how & where the jewelers get their gold.
Also, Peru does not, to my knowledge, have a reputable refinery. Most Peruvian doré bars (from the mines, typically some 60% pure) are exported, many to Miami (!), Miami I believe is the No. 1 US city importing gold -- surprised me when I learned that.
Anyway, if I get news, I will pass it along for our community´s interest.
(And next time, I want to see a gold mine!)
