If the same style of punch was used, different things can alter the mint mark.
1. A very slight tap of the punch can rotate the punch a bit.
2. The depth can be slightly different and make the mint mark deeper into the die and make it wider than others used with the same punch.
3. Circulation can alter the shape by a flattening down of the mint mark altering it.
But if it is the same style, the die/coin may have experienced the above mentioned things.
