Perhaps WW2's rarest cav patch on ebay sold for $713 in ARMY AND USAAF Posted December 31, 2012 That's an easy question to answer; the two that I have! Really not easy to answer and the prices have been all over the place from 200 to 700. To me one of the nicest is the example Patch Johnson has on the uniform with the motto and unit number. As Bob said they are all rare, and if you find one just buy it! The $2.00 patch will always be that price. You never know when you will see it again. Just my advice for what it's worth. Mort P.S. HAPPY NEW YEAR! Thank you Mort.Happy New Years to you too.
