Holy cow...slabbing the slab has happened.
Okay, technically just a holder, but still...
A few years back I joked around I wanted my Ministry of Finance holdered/NGC graded coin put in an oversized slab. It has an NGC stickered grade on it (and IIRC PCGS has sticker graded some too, but I may be mis-remembering). The label had gotten a little roughed up so I (jokingly) wanted it slabbed for protection. The overall size of the MoF holders is smaller than some graded medals.
Here are some old photos of it and you can see the size in relation to a regular NGC slab. And the label.
But lookie what I just found!
So the real question is...can I get PCGS to slab an NGC stickered MoF coin???
