There are and always have been auction sites and auction houses who will get your coins graded for you. You send agree to consign your raw coins to them, send them to the auction company, they in turn send them to the TPG and get the coins graded. You still pay for it, it's just deducted from your check once the auction is completed.
Have any of you or anyone else used this discount raw coin service with GC? And If so, how was the service? And which TPG Company graded your coins most?
I did it once with a gold $1 and a nicely toned commemorative. I let them select the TPG and they went with NGC. The G$1 graded well and did fine at auction. The commem bagged for QC and I set somewhat high reserve on it. It never got any bids and was eventually returned to me (where it bagged several more times on my dime). I paid a reduced fee (maybe $10?) for each coin.
Wow do you have a photo of this commem by chance @mill rat41 ??? I and im sure other members would like to see what this oft-rejected coin looks like.
