Here's a more extensive reason.
I've been advised for years to get my copy slabbed.
I don't want to. Why?
Because when it's slabbed, I will have the OVERWHELMING urge to sell it.
And I don't want to sell it.
I found...for the first time in almost 20 years of collecting....an Albedo #2 in 2007 for 75 cents.
Yes, 75 cents.
(I was due.)
I had it slabbed at WWLA last year, and it came back 9.0.
I sold it almost immediately.
It was the only copy I have ever owned.
And now, I have to replace that copy for my collection.
So, I don't wanna slab this copy, because I will face the overwhelming temptation to sell it, because it will be so EASY.
At least with it unslabbed, it's much, much harder to part with (I'd never, ever, ever sell it if it wasn't slabbed.)
