Vintage Cut Glass Shot Glasses

I found these in a box at a sale. At first I wasn't sure what I had but once at home I opened the box they were in and noticed they were each individually wrapped. Starting to unwrap, I couldn't help but notice the date on the newspaper was January 11, 1943 and from Flat River, Missouri,
Saint Francois County.
These adorable little shot glasses are approx. 1.75 inches tall. They are cut glass with a flower, stem and leaves on both sides of the glass. On the bottom of the glasses, each glass has its own number. These are numbered from 1-28. Some are duplicated numbers and I do not have a sequence of all numbers. There is no markers Mark that I can see anywhere.
These little beauties also have an optic ribbed sides.

No idea what I have. Do imagine they are pretty old. They don't look like they have been unwrapped since being wrapped up in 1943.

Any help identifying these, the value or perhaps someone that would be interested.

I have 19.
