Hi Tanz; The Button with letters is a common modern button ok. The second one however is a 1700's TOMBAC button. it is the predecessor to the Pewter buttons of the 1600's. Value is about $6 due to the shank missing. Most of them are usually blank with no design. They were considered as spare buttons. Yours is a coat button ok. Withb the shank the value is $7 ok. Enjoy. Go back to that site as there are commonly more of them along with other relics ok. PEACE:RONB
