Now, that's a broadstrike! Through a capped obverse die, no less -- heck, is that even a nickel planchet? Or more than one? Weight/diameter?
All very good questions. The coin is slabbed by PCGS and unless the diameter and weight are on the slab label the answers will remain unknown. Although an approximate diameter could be determined the weight would still be a mystery.
Just from inspection, does it look like a single planchet squished thin? I'd sort of assume that if it were anything other than standard nickel-planchet weight, they'd note that on the slab. So given your phrasing, I guess you don't have the slab in hand yet? Not even a photo of it?
Wow, those 2 are very excellent!!! (May we see the reverse of the dime?) Call PCGS & ask them the weight of an empty nickel holder (someone should be able to do that for you), then subtract that weight from the total weight of your slab & that should get you a good approximation. (Alternately, you could free a 5 cent specimen you already have & weigh the remnants of that tomb; then do the subtraction)...if you really wish to know...
It should weigh the same as a normal struck Nickel. The 1919 was a Clamshell Lamination with the piece that was laminated detached.
Aren't all capped dies getting struck outside the collar? I mean, is there a need to give it a brodstrike designation since they will always be "broadstruck". Just asking...
