Crown Jar Age?

[reog]

I have a jar with a crown emblem on front but it doesn't say crown like other jars I have seen and the emblem is different. Seams up both sides of the jar and the number 12 on the bottom. Was wondering if this was a Dominion Crown jar or not and maybe age or value?

Looks like a # 681 in the red book and 35-40. Its hard to figure who made it as there were many glass houses producing them. It should have a ground lip.

In terms of age I'd guess that it dates to roughly 1910-ish. Give or take a decade or so.
