Here’s what Rob cook of Rebeats had to say about it:
“Boy, it’s pretty hard to comment on that limited info. I’m not even sure of the series… I’m no Pearl expert and havn’t really monitored what they’ve put out the last few years, but have never heard of a ‘hard rock’ series. It would take some photos to even hazard a guess. Other unknown factors that are going to have a bearing on the value; number of drums, sizes, color.
“I don’t think there is going to be celebrity attachment value unless perhaps there is some documentation; photos of the previous owner on stage behind Elvis, etc.
“With cymbals, for many years I’ve followed a used value guideline that puts the ‘high used’ value at 50% of retail and the ‘low used’ value at 25% of retail. It should only take a few minutes to determine the retail prices online.
“Hope this helps!”
