Most folks just look at 1914s and 1915s separately.
A few old collectors just worked toward 176 cards, and the year didn't matter.
1914 cards are more difficult to locate than 1915 cards, although the prices don't really truly reflect that. I think that lack of price difference is because few people actually collect all cards of each year. The reason for the difference in availability is set out by fkw above, and is explained in Mr. Lipset's encyclopedia.
The 1915 cards from 145 through 176 have a bit more demand, because the 1914 cards stop at 144.
And if you get a copy of Mr. Lipset's excellent Vol. 2 of his Encyclopedia of Baseball Cards, he has a list of the 1915 cards that are different from the 1914 numbers. In that, the 1914 card #99 depicts Frank Chance of the New York Americans; card #99 in 1915 has Hal Chase with the Buffalo Federals.
So the answer is yes, the Chance card is a bit tougher than normal.
And the pop reports aren't of great value in ascertaining that.
