I buy and sell coins and collectibles through my company, 2nd Markets (www.2ndMarkets.com). We buy, sell and appraise antiques, art, coins, old currency, knives, movie memorabilia, rare comic books, vintage collectibles, and memorabilia of all kinds. I have been buying and selling since the 1970s, BEFORE there was an Internet!

Nowadays, the best way to learn the true market value of collectibles is on the Internet, using an online appraisal site. My favorite is IGUIDE.NET

I find it to be ne of my favorite resources for collector pricing information and collectibles appraisals. Visit iGuide.net

    This is an online business you can trust. Within 72 hours of my contact with them my package was sent and received. My money was sent to my bank account within an hour. This is a great company that I’d have no problems doing business with in the future.

    I can't thank 2nd Markets enough for absolutely everything. They replied to my initial inquiry within 48 hours and from there the transaction was complete within 7 days (weekend included). Communication was great and they answered all my questions and addressed all of my concerns. Will most definitely be referring them and using them again should the opportunity arise.

    My second time around was as great as the first. Simple, Processional, Communicative. You made the total process quick and easy.

    2nd Markets was wonderful to work with. I had no idea how to go about selling items that I inherited and was nervous about doing this transaction online and through the mail. 2nd Markets made me a great offer. Shipping was easy and payment was made promptly. I would definitely recommend and use them again if I ever have the chance. Thank you!

    I came across these old coins I inherited decades ago when doing some life organizing. Ebay said they were worth something, but it didn't seem like that route would actually lead to a sale. Went to a coin shop and they just wanted to pay me to melt them down for their silver. When I found 2nd Markets, they sent me a quote within days that took into account the value of the memorabilia, not just the silver from which they were made, more than it looked like I would get anywhere else. They were easy to communicate with, detailed in their instructions, and facilitated the shipping for free. As soon as they received the merchandise, they paid me immediately. 2nd Markets is easy, trustworthy, and reliable. Would happily go to them again!
