According to Retailer's Information (REV-717) from the PA Dept of Revenue, the following are *not* taxable: * Bullion, investment metal * Coins, investment (numismatic coins and legal tender) Several other sites reiterate that there is no sales tax "on coins or bullion". The Coinologist adds that paper money *is* taxable (?). Q1) So if I buy old U.S. Currency out of state, I am to pay Use Tax on it? I don't know this website, but Golden Eagle Coin goes out of its way to say: "There is an exemption for purchase of coins and bullion, as long as the value is based on the metal content and not the form of the product." Q2) So what does that mean for 5 oz ATB "quarters"? They make it sound like buying the "burnished" version of the 5-ouncers (~$150 or more) would be taxable, but the "bullion" versions (~$100 or so) would not be. @dwhiz ? @V. Kurt Bellman?
