I have to be honest, I wasn't expecting so much of the coin to show. That sticker does look a little off-center, too, but I don't think so much as to be worth much of a premium to die-hard sticker collectors. I do like how the black logo is complimented by the black frame on the slab and how the light reflects off the slab and ever so gently off the sticker, itself. The toning of course is by no means "monster," but I do like that lavender hue around the "A," I think it's NT all the way, really cool, and should fetch a few extra buckaroos when I sell. But for now, of course, hey, this baby remains in the collection, where I and all my collector friends will have the opportunity to embrace and admire it in the ensuing years.
Been thinking about starting my own sticker company for over graded examples. Tossing around the idea of a brown sticker that says "POS".
Why would you CAC a 1900 $20 Liberty? This is a common date coin that has a very high population for the grade. I do not think you will receive a very big price bump when sell time comes. Should have saved your submission for a better date or condition rarity. I prefer the big CAC sticker on the slabed ATB hockey pucks some people think are so neat.
You must be the type who collects coins and not slabs and stickers. Yeah, I heard about your type. I knew you're out there.
