Its the SVDB that has value....
You obviously know your coins!
Personally, my favorites are: Walking Liberty halves, Standing Liberty quarters, and Peace Dollars. Have a smattering of circulation find wheat cents & Indian heads, but nothing high-grade. (i’m in the almost-retired cohort, coins were BIG in the 1960’s and I got back in big-time, in the late 80’s. Feeling good about it all!)
The Cent on the Rover is pretty cool nonetheless! It’s been subjected to Mars atmosphere, radiation, and “blowing dust,”
etc., for 2000 days.
Tangent— I’d love for say,a Musk, to retrieve it from Mars and submit it for 3rd party grading at PCGS, etc. HA!
Amen to that! Coin collector, eh?
