Exhibit Antiques has dated this piece to the 1850s.
An exceptional 19th-century wine glass dating to 1836.
It has a conical bowl with slice cutting towards the base.
Sits on a bubble stem containing a silver four-penny coin dated 1836. Ball knop above a conical foot with polished pontil.

The crown and hammer represent the "Hammermen of Glasgow" which is a charity based on engineering trades founded in 1536 and still exists today. The Hammermen embraced blacksmiths, silversmiths, armorers, sword makers, and locksmiths to name but a few but was incorporated to regulate the metal working trades with the Burgh of Glasgow as well as supporting their members and widows and dependents should they fall on hard times.

Their Moto was "By Hammer In Hand, All Arts Do Stand"
We can't recall seeing another example and the glass should probably be in the Glasgow City Museum.
