Absolutely no communication. Totally disregarded the value I put on my coins. I requested one of my coins back and they refused to send it back to me which cost me a loss of thousands of dollars.
A great site for beginners and experts. I have pura used several times from this and very please with the quality of the coins and the preservations of all the 1800 coins I purchased. Top quality at unbeatable prices. Again thank you.
Any rare coins in your collection? How about your pocket change? Let these guys Check your coins. Wouldn’t it be nice to have that one penny and it ended up being worth a couple hundred thousand..?
I buy, sell and collect US Coins. Well for about 2 years or a little longer I have sent at least 25 photos of US Coins, recognized error coins and non error coins to the NOT so Great Collections.com because they advertise that they have a program that will pay to have your coins graded, auction them off, take their percentage and then send you a check for your part of the sale. They may say the program however they don't do the program. They are only trying to buy your coin dirt cheap and sell it themselves for huge profit margins. When you call them on it, the response is generic and scripted
