I'm a new coin investor and I'm looking to make a profit through buying coins, mostly gold coin at one price then selling them to mainly local dealers at a higher price. Now that I have the info that I need from the greysheet I can better coordinate my plan of attack. let me know some of your experience's. I've seen many different auction websites where coins have been bought way under current bid price and I've seen some sell for way over bid price. Any tips when trying to make a profit this way. Also if you buy through online auctions what website has the lowest buyer's free, I've used greatcollections in the past as there fee is only 10% but, are there any other sites with a lower buyer s fee. You don't have to give me all your secrets just some tips, thanks.
