I sometimes sell guns priced in ounces of silver. In almost every instance, the people have paid me in dollars (most people don't know how to buy silver) and I have added 5% for the conversion to silver, and I use an exchange rate to my favor. I still like to do it, even though it may have cost me a few sales over the years, but I like to still price the items in silver, as it makes a few people think about it, and I have opened a few eyes over the years. I usually price the gun in full ounces, and post the US Dollar and the Euro exchange rates (not the converted price, but the rate of exchange) and make the people try and do the math in their own heads. I sold a rifle recently for 10 ounces of silver, and posted the euro exchange rate at 32.50 / oz. Can you believe the average Joe Schmoe wasn't able to determine the price of the rifle was around 325 Euros without using a calculator!!!!! Most people had to get out their I-Phone, and download an app, and even then they didn't know how to add SILVER to the currencies. They said "I don't know how to figure this out, silver isn't really a world currency, and it isn't in the list".
