By Alissa PaolellaOn a recent Saturday morning, before Ohio Silver Co. opened, a line of customers stretched from the door and down Xenia Avenue. Near the entrance stood the Tin Woman, the silver figure Ohio Silver owner Marcia Wallgren built by hand and the shop’s unofficial mascot, keeping watch over the crowd. After 54 years, Ohio Silver Co. — one of downtown Yellow Springs’ longest-operating businesses — is closing. For all the emotion of these final weeks, Wallgren said she is at peace with her reasons for bidding Ohio Silver farewell. Ohio Silver Co. was founded in November 1971 by brothers Tucker and Kris Viemeister and Kerry Moore, according to News archives.
