Beta cloth patches signed by the entire crew are relatively uncommon. In all likelihood, you're not finding them in dealer inventory. Maybe once or twice a year in an auction.
The lack of "Apollo 11" text on the emblem indicates this is a reproduction beta commercially issued by Owens Corning. The patches issued by NASA were never commercially available, which makes them more valuable. Also, I believe this patch has been trimmed. That said, the patch in question is still quite desirable and uncommon.
Thanks gentlemen. My research indicated that it was a reproduction beta cloth because the "apollo 11" was missing and that it was trimmed. So I agree with Mr. Zipper.
From the sound of it, it is uncommon. But what about authenticity and value? Also William brought up a good point about the price of admission or if theyvare truly rare. I would love to hear the answer to that.
