Trying to pick the brains of you numi pros out there on this one. One of my 1916d Mercury dimes is slabbed
by ICG and graded AG-3. I was wondering if I were to send it to one of the upper tier graders, like NGC or PCGS,
to be regraded, would it increase the value of the coin, all costs considered, or would I be taking a chance that
the coin would be graded down?
Or should I leave it alone as it is?
I don't have any way to take quality pictures to post. Any advice is appreciated!
