Bidding For Auction 101 Open In:

MintProducts Auctions is a division of Jeff Kierstead Rare Coins LLC. We began holding live Coin & Currency auctions in 2015, but then during the Covid-19 pandemic, made the transition to online only auctions. Now we exclusively hold monthly online Coin and Currency auctions. Our auctions feature hundreds of unreserved lots with bidders numbering in the hundreds too! MPA’s roots go as far back as 1984, when our president Jeff Kierstead ran his first coin auction. Jeff was also a founding partner in another New Hampshire coin auction company from 1993-1998.


MintProducts Auctions sales always include an excellent selection of Rare Coins, Bullion, Type Coins, World Coins, Paper Money (Currency), Key Dates, Silver Dollars, Modern Issues, Tokens + Medals, Copper/Colonials, Early Proof Sets & Mint Sets, Attractively Toned Coins, and all types of Gold & Silver Coins!
We’re always accepting consignments for future sales, so if you’re looking to sell coins, currency, or exonumia, etc., we’d love to work with you!

    Adam is Jeff’s son and has been attending local coin shows with his father since he was in kindergarten. In those early years, Adam would earn tips for cleaning the dealer’s glass showcases or getting them something to drink. With Adam’s hard work at the shows, his tips would often surpass what some of the dealers would earn! In recent years Adam worked for where he managed inventory and oversaw order fulfillment. Adam became a partner in MintProducts after his father sold that portion of the company in 2017. With the auction business growing, Adam rejoined his father at MintProducts Auctions in 2021. Adam currently oversees the handling of auction lots from their arrival at our office to their shipment after the auction and everything in between.
