Caveat Emptor is indeed the best policy. Purchase from knowledgeable and reliable dealers who provide lifetime guarantees for the items they sell. Before starting any collection, read about the area of interest and purchase books related to coins, learn everything you can. Knowing the average weight of an authentic item can save you from making a bad purchase. Granted there are some items that are authentic and underweight due to having been in the ocean or clipped at some point in time. As you progress in your knowledge you will have a better idea as to what you are purchasing.
Also, inquire as to the item's provenance. If the item has a traceable history the likelihood of it being a problem is slim.
