Besides comics, I've dabbled with non-Sports cards, coins, and paper currency. For a while I was an avid collector of vinyl, especially 45's, with emphasis on the picture sleeves. Also sheet music from 60's. I once talked to Borock about the possibility of CGC grading sheet music but he said it was too small a niche and would not be worth it. Now, it seems like they slab a lot of different things. Whenever I went off on these collecting tangents I always came back to comics, obviously what I enjoy best. I admire the broad stroke of your collecting scope. I see it as you are collecting a time period, as opposed to any one one genre. For me, whenever I expanded my collecting scope, the biggest challenge was storage space. How do you handle that challenge ?
