3rd Anniversary Pulse Shooting Nightclub Owner Memorial

For example 9th 3rd 301st what do we call these special sounds? But i heard that 3rd is something like spoken form and it's grammatically correct to use 3d. When we use words like first, second, third, fourth or 1st, 2nd, 3rd, 4th, in sentences, what will be the best way to write these?

When were numeric contractions for ordinals first used, as in 1st, 2nd, 3rd, 6th instead of first, second, third, sixth?
