the font is different - look at the final 8s in my composite above - the variant 8 is neater and symmetrical So, although it may be very hard to spot, and invokes little interest, it is as significant as the open 3 for 1903 whether the change for either year was deliberate, or a busy mint worker accidentally used a numeral punch designed for a different coin, we will never know. the variations of 3 in 1863 pennies may actually be due to where the coin was struck (by the Royal Mint, Watt or Heaton???) interesting question, why are coins dated anyway? or more to the point why are the dies dated, as there is no guarantee as to when a coin was actually struck?
