Seth Chandler is the owner and Chief Numismatist of Witter Coins. He started collecting coins when he was four by placing Wheat Cents in blue Whitman coin folders given to him by his parents. Things started getting serious when Seth was ten. Money earned from mowing lawns was used to buy coins at his local coin store, Edgewood Coin Shop. Seth spent so much time at Edgewood; they offered him a job, working there from the age of 14 to 18.
Seth has been an avid coin collector for over 40 years and his collecting interests includes early United States gold coins and all coinage minted at the three San Francisco Mints. When not playing with coins, Seth spends time with his three young children and lovely wife, Jen.
Sean Dinsmore, Numismatist. Sean grew up in Roseville, California and was first introduced to coins by his grandmother, who cataloged the world coins that his grandfather brought back from service in the Merchant Marines. After graduating from San Francisco State, Sean returned to the coin hobby and eventually made it a career. His personal collection consists of earlier US type coins, Morgan Dollars, and Foreign & Ancients coins. When not in the store, Sean enjoys cycling and is a diehard San Francisco Giants fan.
Luis Ramos, Numismatist. Luis has been collecting coins since he was eleven, after he was given a collection of circulated Mercury Dimes by his grandmother. This one folder of Mercury Dimes spurred a lifetime interest in collecting. Luis is currently assembling sets of Proof Mercury Dimes, Classic Commemoratives and DMPL/Toned Morgan Dollars. He has completed courses at the American Numismatic Association on Advanced Coin Grading for four years straight. Luis has also successfully completed the Gemological Institute of America Diamond Grading Lab Class. Aside from coin collecting, Luis enjoys auto racing, collector cars and photography.
