I look at bullion coins as an ounce of silver and gold and nothing more. I'll respect those who like them graded but their reasoning, frankly, escapes me.
Bullion coins are only valued for metal it possess and no more no matter how long you have had it.. alias silver porn
If I was in the market for a 1 oz gold coin, and I had my choice between a certified coin and an uncertified coin, at virtually the same price, I'd go for the certified coin. That means the certified coin, IMHO, might be easier to sell, but not that anyone sending it in for grading is actually recovering their expense for doing so. If I bought a run of the mill certified ASE, I would probably crack it out and put it in a roll to save space.
Low mintage perfect grade will make it a unique coin ! http://www.ebay.com/itm/1995-W-Proo...138374?hash=item1c5dc2e686:g:tF4AAOSwNgxWDDlW
No I have all raw, but I'm thinking about it. After all, I have a bunch that I've cherry picked over the years and now I'm definitely thinking about it after seeing what some are bringing now. Why not?
I just bought an MS-70 $5 Gold Eagle...because it wasn't much more than the bullion. Also, because people pay more for the slab if/when I sell it. Higher "profit" for me, and an easier sell because of the "warm, fuzzy feeling" they get knowing it is genuine (according to the TPG).
There's only 24 of those from PCGS. There are a lot more than 24 people putting together ASE sets who get 70s when they can.
