Hello i work in a coin shop in Temecula California and have been seeing lots of fake gold pamp suisse 10g bars in package come over the counter, but i i identify them as fakes by weighing them and matching them up with the correct weight still in package. I know there are people making some with the right weight in package but have the wrong dimensions on the bar which is almost impossible to measure without taking it out. i haven't bought any fakes so far but plenty of shops around me have lost thousands of dollars from these fakes! does anyone have any tips on how to identify fake bars in plastic without ripping them out????? i also came across a fake 20$ liberty gold coin that looked pretty close to the real ones, but weighed a couple grams off so i passed on it. i made a cheat sheet with all the weights and dimensions on common gold coins and bullion such as krugrands, sovereigns and  such for everyone working in the shop. look out everyone and always check your work when buying gold!
