I found this old bottle cork in some boxes belonging to my grandparents, who lived from the 1880s to the 1950s.  They were collectors, so this could have come from anywhere.  It appears to have “1/4 pint” impressed on the front.  Any information (date, type of bottle it would have been used for, value etc) would be appreciated. Both ears are broken and it obviously has significant wear.  Thankyou!

Alas, my photos are not attaching properly, even though I have resized them as needed.  But I will keep trying.
