I was looking at the prices for PCGS services and noticed that it varies according to the coin value. Does this mean you have to know the price in advance? What if you overpay or underpay? Or let's say you have one of those "million dollar coins" that we see a lot here in CT, and it turns out to be fake, you lose the $300? Edit: use better wording
Yep, no refunds on the grading fee if you sent in junk Have some idea of it. If you put a good faith value it's generally fine if say you send in a coin economy and it ends up being worth like $370 instead of the $300 limit. Now if you try and send in a four figure coin you'll get up-charged
100% this. There is some reasonable wiggle room on the caps. You should have an idea of the value of your coin, but PCGS reserves the right to adjust the pricing on the fly. Meaning, if you send a 1913 V nickel as economy, they'll smile and charge you the appropriate fee instead, based on their evaluation.
