Most of the auctioneers in the market specialize in selling coins and bank notes. Some of these auction houses deal in selling coins from United Nation, and some may sell ancient and foreign coins as well. These entire auction houses have one thing in common, they want to sell coins and bank notes only.
Once again the question of which market to choose arises. For example, if your coin collection consists of coins from Pennsylvania, and you are selecting a market from Chicago to sell it, you will not be getting the best price there.
Similarly, if you have a collection of coins of a $10,000 value, and you are willing to sell it through the local auctioneer, you will not be satisfied with the result for sure. If you have such a valuable coin collection, then the international market place is the best area for selling your coins to get the most profit.
