Weakly Struck Coins from the Mid 1920's

It seems to me that the coins of the mid 1920's really have thier share of problems that are not seen before then or after then. Since I had no gripes to put up here or any place else some reading was done to try to figure out why this might have happened. Below are some explanations of what is done by humans before a coin is struck and a combination of these just might explain why the dates are basically weakly struck.
Annealing is the heating of the metal followed by the slow cooling of the metal which softens it thus aiding in the striking process. If this is not done correctly the coin probably will not strike up correctly.
Basining is the polishing of the die to create a slight dip from the sides toward the center, a very exacting process that affects the metal flow when the coin is struck. If this is done incorrectly the coin will not strike up correctly either.
A couple of other items come into play also. Die spacing and worn dies play a part in weakly struck coins.
What do you think was the main reason within the series you collect that caused weakly struck coins from this period ? Myself in the Merc Dime series, and especially the date of 1925, I believe weakly struck coins were caused by the way they were Basined. I say this because usually the obverse was weakly struck and the reverse was acceptable. If it was the Annealing process wouldn't both sides show weakness ?
Anyway this is just a thought as the coins minted at the San Francisco Mint in 1926 , Lincolns, Buffalo's and Mercs, certainly all have the Weakly Struck problem. Was there incompetance at the Mint at this time or was there a change over in personnel ?
Anyone else have any ideas ?
