I just bought a PCGS slabbed New Mexico silver state quarter in PF-69 for $11.00. Since the cost of slabbing is around $10.00 would this be considered a good deal? I imagine the seller was hoping for PF-70 but instead got PF-69. Would collecting slabbed PF-69s be a good idea - since there are quite a few collectors who hope for PF-70 but end up PF-69s.
IMO, if you are thinking investment, the answer is NO. If you are thinking collection, the answer is YES if that's what interests you. A PF-69 set of state quarters would be an impressive sight.
I saw on ebay a complete set of silver and clad proofs in PF-70 sell between 10 and 11 thousand dollars. I would like to have a set each of these as a collector, so slabbed would not interest me. As always the "70" means a lot to some people, the "69" I'm not sure. Assembling a slabbed set as a collector I can see where it could be fun, as an investor that may be a different story.
If they are not slabbed by a major TPG you will not be able to convincce anyone that they are MS-70, or even -69.
I think the PCGS state quarter slabs that have the flag on the label are kind of cool for some reason. I'm contemplating picking up a few of those.
I don't see a reason not to. From what I have seen, most slabbed silver proofs (NGC and PCGS) in PF69 aren't hugely expensive. The PF70 coins are the coins that command the insane prices. If you want to put together a slabbed set graded 69 then go for it. The coins would look very uniform in the slabs and it would be an attractive set. It might be a bit cheaper to pick up the sets in the original government packaging...but if you want the slabs then go for it. I personally can't tell a difference between the proof 69 and 70s.
