    Might be easier to make it with a pair of 74LS192 BCD up/down counters.

    You would also need some gate function to detect when the 50th count was reached. The output of that function would be used to reset the counters to 00. In that event, you would never actually see 50 in your display. If you could allow for the 51st pulse to be the one that reset the display to 00, the gate function could be modified to allow that also.
