1.75". Curl has name of maker Midwest Badge. Reverse has .25" cello split next to the collet but the celluloid still lays very flat and does not make any noticeable edge bump when viewed from the front. The front of the piece displays Extremely Fine but on very close inspection there is just a tiny bit of light stain at the lower left touching the letters "IDE" of "President" as well as a couple of very tiny dots around the eagle's wingtip and a tiny mark around the letter "T" of "Truman." We must emphasis how well this small bit of aging blends as the vast majority of the piece still is in outstanding condition with perfect centering and full gloss and color. Hake #6 with Revised Prices 2004 guide value of $800.
