Hey guys, I don't know much about vintage skate stuff but I came into buying 250 pristine, uncut skate deck blanks from the 80's. I could have the guys that shaped them at the time write them up and I even have the original stencils. They are all stencils of the Powell boards and others during the time. If anyone could quote their worth because there are so many I cant hang on to them. Should I cut and sell as my skateboards which I wanted to do or get authentication and sell uncut? Thanks!
