The Mint struggled mightily in difficult circumstances, although presumably, the institution went on to produce more than 800,000 pieces of the 1½ pence for the calendar year 1834, since the order to authorized its mintage was dated September 12th. This is my hypothesis of why, we have not been able to see a specimen of 1835 non-over date as of today. Is perhaps quite simple.
Looks like that the Mint in two separated strikings, coined 240,00 pieces dated 1834 from November to December, 1834 and in 1835, 400,876 pieces dated 1834 together with the production of three halfpence pertaining to that calendar year, for an astonishing quantity over the 1.1 millions coins produced.
Since there was great demand for the 1½ pence by the colonies in 1835 and the officers of the Royal Mint felt under pressure and thought it was not worth the time and effort to make a new punch, they probably took the decision to use leftover reverse dies dated 1834, re-tooled them punching the number 5 overlapping the existing number 4, creating one of the most famous curiosities of the British coinage.
This over date coins were released anyway and shipped out to Bahamas, Jamaica and Trinidad, to the best of my knowledge. Perhaps the explanation of just a few reverses of 1834 & 1835 used, or that I have been able to list.
I personally examine more than 50 examples of 1½ pence coins dated 1835 since 2007, and every one turns out a over-date. It's the Reverse 1, apparently erroneously attributed as the famous non-over date 1835, fact claimed by many authors, however if such coin exist, it's the rarest of all 1½ pence ever minted, being unique or a few in existence, if not a fake.
Δ In Reverse 1, especially if the date area is covered with dirt or other substances because such coin has been circulated for a long period of time, and has signs of worn, [left image], when looking the numerals through a microscope, [right image], vague details of a 4 beneath the overlapping 5, still visible on its left side and/or its baseline.
