JM Bullion, Provident, Modern Coin Mart, Liberty Coin & Precious Metals, Silvertowne, Gainesville Coin, Goldmart and Monarch Precious Metals are good.
I've personally dealt with: JMB, Provident, MCM, Liberty, Gainesville, Goldmart and Silvertowne. The only one I can't vouch for is Monarch but I have heard they are quite good as well.
Do you "work" for TOPPS?
Since no one answers phones, emails or customer service inquiries via the website or facebook, hit me up about that 2012 Jim Brown Five Star Autograph. Thanks! Initial inquiry sent Jan 2015. Months with no response - 3.
