Your frameless eyeglasses
by: Anonymous

The mark you are speaking of is actually a "C" just like you said with the one serif, over an "O" and again, over an "A". This is a manufacturer's mark and represents "American Optical". The mark off to the "right side" represents the gold content.

In your case, if I am reading it correctly, the mark you describe would stand for 1/10 12K Gold Filled. All American Optical eyeglasses with the same C, over an O, over an A are from circa 1889 to 1911. If your eyeglasses were made of solid gold, they would read either 8K A.O.Co.+ ( 8 karat ) or 10K A.O.Co. with a round mark and a horizontal line through the middle (resembling a pill with a cut mark) or A.O.Co.14K (of course 14K Gold ) From circa 1911 to 1927, your American Opticals should read "Wellsworth" with the same marks for gold content mentioned earlier. Circa 1929-1942 have a capitol A partially over a capitol O with the same marks off to the right as I mentioned earlier.

Circa 1943 eye glasses have the same AO mark as mentioned immediately above but is surrounded by a shield. If your eye glasses have nose pads ( no matter who made them ) they cannot be any older than circa 1922, as there were no nose pads on any eyeglasses manufactured before 1922. The curled cable type ends were not invented until 1881 and were actually invented by an employee of American Optical. I hope this helps..... Thomy

American Optical Company

I would guess that the A is actually inscribed in O (not a C). This mark would be for the American Optical Company.

Maker's Mark on Antique Spectacles

Hi there, and what a fascinating area to collect! Not antique jewelry, but non the less I'm sure it would be very interesting when you consider the history of eye glasses goes way back to the 13th century!
