Are the over the tops a reasonably rare item. I forgot that I had a pair at my parents house that I got along time ago from a friend that gave then to me in exchange for cutting my hair in a nowhawk. Cause ya know they've got that split in the middle and a mowhawk fits nice right through the middle. Anyway I was just looking thru ebay and people are trying to sell these for $700 to $900 with box. Are they really worth that now? Or is that just ebay prices. Was gonna have em shipped down to me and wanted to insure them but wasn't sure on the value. Thanks
