I have six pepsi coaster

[davidb43]

I have a set of six pepsi coasters they are cork on the bottom. Made of brass and leather.I cant find anything like them in my search. They come in an oak box and are in great condition. Through my research the logo on them was in use between 1905 and 1926 I believe. Was wondering if anyone knew anything about them and what they maybe worth. Cant figure out how to post pics here so if you need pics let me know.
