Four Vintage Glass Coasters

Two of these have a letter F in the middle of the daisy starburst design which I believe stands for federal glass. The other two don't have the F mark and are not exact matches but are fairly close. Would be great to use as coasters, trinket holders, or saucers for small plant containers. One of the ones with F does have a small chip on the bottom of the coaster, as shown in the last picture. Here is the information below I found on the internet regarding Federal Glass: You can identify Federal glass by looking for the "F" inside a shield mark or by identifying the pattern.  Look for the "F" inside a shield The Federal Glass Company's hallmark is an "F" inside a shield.  The mark is usually located on the bottom of the glass.  If the glass doesn't have the mark, the company may have attached a paper label that rubbed off.
