A nice pair of 19th century mercury glass tiebacks with original pewter or Britannia metal collars.
They measure 2 1/2" in diameter by 3 3/4" long to the end of the screw post. Both tiebacks are in very good condition. They both retain their bright, shiny mirror-like quality. One has a minor surface scratch on the top of the tieback and some silver loss, or cloudiness, near the collar and an old lead repair inside the collar.
I would date these tiebacks to the last half of the 19th Century. The perfect accessory for either the modern or the antique decor!
