Hi, we have 12 of these annual Christmas bells ourselves. They are silver plated and each one comes from a different year, part of a 12 piece set. Unfortunately, more information is limited since the New England Collectors Society shut down in the 90’s. I’m thinking these bells ran from 1980 or ’81 to 1991 or ’92. Each came with a certificate of registration which states they are “serially noted, hallmarked, and registered by the New England Collectors Society.
On a separate note, we take these out every Christmas and have lost track of which bell is which. We only have pictures for three of the bells that tell us what it is, though we have registrations for several more. I think my grandma threw some of the registrations away before my mom inherited them, though. If you know which ones they are associated with, we would appreciate that information.
