Population Reports?

Hello all,

Just a question I've always had and often ponder about. Many people (like myself) do not care for slabbed coins and others "crack" them open and resubmit them or cross-over to other TPG's in hopes of a better grade. How does this affect the population reports? Is it minimal? or major?

I only ask out of curiosity.

For example: Let's use the 1914-D Wheat cent, (I know a whale of a coin in wheats at least.)

Currently PCGS has graded 132 in MS64 and 59 in MS65 an $8500 difference (per their price guide). I find this curious. If it were me and I decided to send my 1914-D and got it back slabbed MS-64 it would be worth another couple of go's for the chance of 1 more grade and an $8500 difference. Crack it open and give it another shot which I'm sure happens, thus directly affecting the population report, (same coin shows twice or more times in different or same grades.) Just curious on thoughts about this.

I also find it odd that they have 1 graded MS62, an odd grade obviously.

Another reason to "buy the coin, not the slab".

PS - Also curious to read some literature, if there is any on this topic if someone would point me in the right direction.
