Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this Radio-Dakar QSL card that just sold on eBay for $1,195 US:

As Dan stated…“Holy Crap!” 

Checking out the bidding history, it appears there was definitely a bidding war going on, with the buyers entering substantial bid increments.

This QSL card started out life on eBay at $9.50 with free shipping.

Amazing.
