Proof Mercury Dime Question

I just looked at the PCGS website and all they list for proofs is the CAM option. Interesting. Someone with more knowledge in the series should be able to answer a little better, but it seems to me that they are doing as you suggested and assuming that the strike should have FB. Forgive my ignorance with the series. It also makes me curious while we're on the subject as to why you couldn't have a FB designation with circulated coins....Especially those in the mid to high AU range.

Just Carl, I actually do have a Mercury dime album for my Mercury dimes but you are correct in that there is no spot in the album for the proof dime. I just meant it would look nice in my overall collection. I have several coins in slabs and this would fit very nicely alongside the other slabs.

While we are on the subject of albums, does the Whitman Lincoln Cent album have spaces for proofs?

Unfortunately yes slots for all proofs. The Whitman Album also has slots for the 22 Plain, 55 Double Die, 60 Large and Small dates, 70S large and small dates, 72 Double Die, 95 double Die and probably soon will have all the RPM's ever found. Slight exageration. OOOPPPSs, forgot they have slots for all the 82's too. Most of my Whitman Cent Albums are 10 pages and difficult to close. I do have some that I made myself from blank pages and left out all the errors and proofs. Also, made an Album for all proofs of all denominations. Nice thing about the Whitman Album covers. Large enough in most instances to add many pages.

You would be better off contacting Whitman for blank covers and pages and make your own Album. Also, see if they still have those Gold Letters/numbers. You just place the sheet under a slot, use a stick thing to rub and then left. The thing you rubbed is now on the page. All takes time but lots cheaper than buying a lot of proofs.
And if your really lazy and don't care, you can just use a black felt tip marker for the dates. Or just leave it all blank and put the coins you want, where you want.
Like I said I've made lots of my own type of Albums.
Another easier approach but does not look real great is to purchase a normal Whitman Album. Then purchase a dark blue Sharpie Permanent Marker. Blue out all the info under the slots and write in what you want with a Black marker. I've done that also. Doesn't look real professional but so what. They are all mine, mine, mine.
