Do you have electronic testing equipment to verify the nuggets are real? I'd stay far away if you don't! The premium you pay for smaller coins will be worth it when you go to re-sell. Coins are of a standard weight, standard diameter and thickness, etc. Fake nuggets are alot easier to make and because the weight isn't standard, you could be buying a 1/2 gram of pretty brass and you wouldn't know it without a tester.
Buy a $20 digital gram scale on ebay. Learn about the coins you want to buy and weight them, check the diameter and thickness and if all checks out, you can rest easy
99% of all faked coins are numismatics, and the ones that aren't are either too light, too thick, or too wide.
