Yes and no.
The SV (and Chicago) Wilson Pro Staff midsize is now a collector's item more than it is a racket to be used. The pro connection to players like Connors, Evert, Edberg, Courier, and Sampras has bolstered the demand.
Also, to those that used the frame in the past, there is the nostalgia factor.
But......the SV PS85 is a tricky one because it has a very distinctive feel that many people who don't care about the pro connection or didn't grow up with the frame have come to appreciate.
If you think the $200 is a high price, a "new" one - never used, never strung (or intact original stringing), case with hang tags - will go for over $1000.
