Is price per point an indication of future value?

I recently acquired two coins; an 1893-CC Morgan dollar and a 2006-P Colorado state quarter. Comparing the two is a little like apples and oranges but I find the point values assigned by NGC to be skewed to the advantage of the modern coins.

Coin Price Points $/Point

1893-CC $5,100 2,786 $1.83

2006-P $30 620 $.048

As you can see, if your focus is to amass a large point total, then concentrate on modern issues where you get the most bang-for-the-buck(about 5 cents a point). Personally, I find modern issues to be ho-hum compared to the artistic issues of the past. Mind you, this is just an opinion, but give me a 'buffalo' nickel or a 'mercury' dime, in almost any condition, any day over a 'Jefferson' or a 'Roosevelt' in a high mint state. I should think by now the mint should be able to manufacture near perfect coins as a matter of routine.

I am assuming that NGC registry point values were established some time ago and may not reflect the actual scarcity of a particular coin as of today, last week, or even last year but I think if you compare coins of the same era, the ones with the largest 'spread' of $/point have probably appreciated the most and more than likely will continue to outperform the market. Is this conjecture a stretch on my part or a total fabrication, i don't know. Would appreciate your thoughts. Thanks for reading and happy collecting all!
