1 Gregorian Copper, hand hammered — marked

* 1 Gregorian Copper — apparently unmarked

* 1 Bridgeport — marked

* 1 copper ashtray with the unusual raised geometric emblem — unidentified

That’s actually a better lot than four completely unidentified ashtrays. Gregorian Copper has a recognizable vintage following, and comparable Gregorian copper ashtrays are currently being offered around the $15–$35 range, with some unusual examples higher.

I’d change the listing to:

Title:

Vintage Copper Ashtray Lot of 4 – Gregorian Copper, Bridgeport & Unmarked

Description:

Vintage lot of 4 copper ashtrays, including two pieces associated with Gregorian Copper, one marked Bridgeport, and one with an unusual raised geometric emblem.

One is clearly marked “Gregorian Copper – Hand Hammered” with a model number. Another appears to be Gregorian Copper but is unmarked. One is marked Bridgeport. The fourth has a distinctive raised geometric design but no maker’s mark that I can find.
