Hello, lived outside of Boston for 15 years and use to attend the Bay State
Coin Show regularly.
That was a long time ago. Never joined a club and to find an exclusive ancients group may be difficult.
Found this website for you to locate groups in your
area.
http://www.thecoinlook.com/clubs.htmThe most promising would be this one it seems
Boston Numismatic Society, Waltham, MA
Club Meetings: 2nd Tuesday at 7:30pm. (except July and August)
Location: Trinity
ChurchYou'll have to confirm.
Good luck....you can always form a group yourself!
Shouldn't be too difficult, especially in Boston with MFA.
