Quoted from xTheBlackKnightx:
Younger enthusiasts might not recognize the coin, and I attached a photo
I worked my way through college as a Denny's server back from 2009-2013. One day, a lady paid her entire bill, and tip, using a stack of S.B.A. coins. She left a huge pile right on the table. She also had some bicentennial Eisenhower coins mixed in. Weird.
I always liked them though, with the whole Apollo 11 insignia on the back.
