How accurate is Heritage Value Index for generic common & semi-common coins?

Specifically Half Dimes, or if you don't follow them (wich most of you don't
) what do you find for your series?
I'm not talking PQ or rare.. just your basic ms+ coins

I paid $177 for a nicely toned example. Its an accurate valuation in my book, of course its only one example.

I can't find any heritage value index on their site, i'm thinking it's a DB they have for use in their auctions but i'm hoping i'm wrong

go to heritage home page
click on Sell on top 5 page links (it is the 3rd)
on right column 2nd from bottom Heritage Value Index
free but need to be registered (so you can bid and get spam
They have values for grades up to the ultrararities
I find it is a more accurate price guide than PCGS - does that say much?
In my experience I have rarely if ever seen a Morgan dollar that I was interested in sell within the range given which is why I stated earlier that if you can get the coin within that range you likely got a good buy. I expect if a coin is not bid up into the HVI range then it is considered not sold.
