It's not only in the obverse legend, also in the reverse legend and there are a lot of other major and minor differences. The MB# 100 has
- An extra inner ring around the shield (this extra ring also occurs on the obverse).
- A smaller shield.
- 4 larger horizontal bars in the upper left quadrant while the MB# 118 has 6 larger horizontal bars.
- Smaller swords in the center shield.
- The center shield is divided almost in half while the upper part of the shield of the MB# 118 is about 1/3rd.
- The MB# 118 has granulated vertical bars in the lower right quadrant.
- The MB# 118 has larger rings on both side of the shield.
- etc.
Of course it's always difficult to compare different dates, especially for older coins. These difference might be a date thing in stead of a type thing. Before you jump into conclusions you have to do more detailed research.
