Q: I’m considering selling a silver tea service to someone who buys gold and silver items. I’m now wondering if the set may be worth more than meltdown value. The sugar and creamer are marked “925 Sterling” on the bottom. The set’s tray is worn and all I can make out in the first line of the mark on the bottom is “rlboro Pla.” Under that is, “by Morton Parker, Canada, E.P. Brass, lead mounts.”
