    A very nice transaction, as well as a honest and fair price. The whole transaction was seamless and very timely. I have a few more items I plan to offer for bids. Thanks again for a great experience. Glenn.

    Working with Jon and the people at 2nd Markets was an overall great experience. They were very transparent, efficient and communicative throughout the entire process. They offered me a very fair price for some Franklin Mint items in my collection that I was interested in selling. They did everything they promised! I would recommend them highly for anyone in a similar situation.

    Ed Baier

    There are not many coin dealers or collectors in Alaska. I found 2nd Markets on the internet and it worked out perfectly for me. They are not a 'melt for silver' company like many are and that was important to me. I received a fair sell value, one that Mr. Jon Warren and I agreed upon. The selling, shipping, and payment all went smoothly with no problems. They encouraged me to check up on the company. I would most definitely recommend doing business with 2nd Markets.

    2nd Markets was a very good choice for us in finding a buyer for some estate collectibles. E-mail bid/acceptance, free shipment & payment were all completed within one week with no exceptions. Bid was fair and the process could not have gone smoother.

    You all were great! I spoke with Jon on the phone... his expertise and help were invaluable. The steps to ship my item were easy to follow. And a check was sent the day received. Couldn't have been any easier. Everything was so professional. Very impressed with this company.
