What this coin looks like (obverse, reverse, mint mark location, special features, etc.): The 1835 Capped Bust Half Dime had a Large Date and Small 5C variety as depicted above.
There were two major varieties that dealt with the size of the 1835 date on the obverse of the coin and two major varieties that dealt with the size of the "5 C." on the reverse of the coin. This made up 4 different available combinations of varieties. Depicted below is an example image comparing the differences between the Large Date vs Small Date and a second example comparing the differences between the Large 5C vs Small 5c 1835 Capped Bust Half Dimes. It is fairly easily to differentiate the varieties:
