Message:: [QUOTE="900fine, post: 233156, member: 6036"]Hmmm... personally, I wouldn't do that. The PCGS values tend to be about 40% high. Changing grade by one point can swing the value either much MORE than that, or much LESS. In either case, it often gives a misleading price. For instance, let's look at a 1923 Saint. In lower MS, it's worth not much more than bullion. The price barely changes with a point or two in grade; it's common stuff. Here are the real values (I'm using greysheet). AU58  $690MS60 $700MS62 $720 Let's say you were considering a MS62. If you use PCGS guides and dropped down a point to MS61, PCGS says that's worth $900 ! WAY overpriced. You could pay too much. That's b/c in these grades, we're in a "flat' region of price, where +/- 1 point has almost no effect, so dropping a point won't overcome PCGS' 40% inflation. But let's say you're considering a MS65. For this date, that's the "break point" where the price skyrockets. It's a condition rarity. The real greysheet value is $3,300. Drop down a point to MS64 price, and PCGS says $1,325. No way you get a 65 for that, so again the method breaks down. Better to forget PCGS entirely and use their prices only for shipping insurance values, where unrealistic high prices mean a little extra insurance cost at worst. That's where I go for values. That and Teletrade and greysheet.[/QUOTE]
