Hi Mike, welcome to the forum. I guess you got this info from Collectors' Coins 2008. I hadn't noticed it before, but the mintage figure for 1947 contains a typo, the actual mintage figure for coins sent out by the mint in that year should be 52,220,400, so not rare at all. In any event, looking at the prices, 1926 is far cheaper than 1894. As 1894 pennies were in circulation for far longer, the average grade they turn up in is much lower, hence anything in fine actually has a value whereas for 1926 pennies, fine coins are commonplace and are worth literally nothing. You should also take mintage figures with a pinch of salt, as they do not refer to how many coins carried a particular date, but to how many were actually issued in that year - many of which will carry the previous year's date. Similarly, the following year's production may include coins carrying the date of the current year. You shouldn't find that 1926 too difficult to lay hands on.
