9. Make an Offer
Believe it or not, there are many collectors who never do this. They pay the asking price without even attempting to make an offer. Many collectors don't know this but at coin shows more than half the dealers will accept offers on their coins, if reasonable. Most other sellers outside coin shows will also consider your offer and usually accept it, if reasonable.
8. Offer to Pay by Money Order, Cashier's Check or Cash
Most sellers hate PayPal and credit card fees. If you offer to pay them with a check or cash it means more money in their pocket. Also, many times credit card and PayPal transactions can be reversed by the buyer months after the transaction. This is another reason sellers try to avoid these payment methods and prefer a money order, cashier's check or cash.
7. Be Prepared
Keep in mind that many sellers are great salesmen, meaning that if you try to make a deal without proper preparation, you and your wallet might regret it later. If the seller seems too pushy, you can always let them know you need to think about it and will be back later.
6. Do Your Research
See what other coins have sold for or are selling for (PCGS' Auction Prices Realized is a great resource). If you find another similar coin, tell the seller where and what you found, and ask if they can match or beat the price.
5. Give Up Your Return Privilege
Many times I have managed to knock off 5% or more by letting the seller know that I don't need a return privilege. This assures the seller that it is a done deal and there will be no more hassles. This tactic also frees up their money rather than keeping it on hold.
4. Trade In Other Unwanted Coins
Many of us have unwanted coins that have just been accumulating dust over the years that we don't want anymore. At times they are just not worth the time to try and sell or you are just too busy. Here you can offer the seller the unwanted coins in trade. You may end up getting rid of some unwanted coins and at the same time, save some money while buying a coin or coins that you do want.
3. Find Distractions on the Coin
Unless the coin is an MS or PR70 perfect coin, the coin should have some distractions. Focus on these flaws when discussing the coin with the seller. Of course, do not offend them saying it is an ugly coin. You can let them know you like it regardless of the distraction(s), but because of it, you are offering a little less than their asking price.
2. Walk Away
If you make a reasonable offer and the dealer refuses it, say thank you and walk away. They might change their mind once you start walking away. I've had this happen to me many times before. Worst case scenario is that if you really want the coin you can come back later and pay the seller's price. However, use discretion, as sometimes some coins can be sold by the time you get back. So, if it is a coin you really want, and at a reasonable price, you should probably just buy it. You will risk losing a coin you really wanted just to try and save a little money.
1. Be Polite
My number one rule in buying coins is to be polite. You never want to offend a seller by insulting their price or their coin. Always be polite and respectful and even throw in a smile from time to time. For the most part, most coin sellers or dealers are nice people. If you treat them right, they will treat you right and more than likely, give you a better deal or work with you again in the future.
I'm sure many of you have used other methods to help you get better deals when buying coins. So, use all the techniques that you think work best for you - the bottom line is to have fun when buying coins. But remember, if you can get a better deal when doing so, it can definitely be even more fun!
