That pattern of wear, with the central part worn away, is fairly typical of well-worn Victorian coinage. I've got several British coins of the period with nothing left in the middle like that. Other coinages show the same thing; check out
token #1 in this thread. The central area's supposed to show the date "1816" and some scrollwork, but all that's left in the middle is a trace of the "8", while the surrounding text is still perfectly readable.
As for the funky-shaped date, I'd assume it's just taken a couple of "knocks". There's nothing listed in Spink about a variety with different-shaped numerals.

Alas, that's a problem with Krause (and many other catalogues). Fortunately, the British catalogues like Spink normally do indicate the die axis. The standard symbolism, in books that do indicate the "normal" die axis for a particular series, is two arrows up ^^ for medal orientation (like Australian coins) and arrows pointing opposite directions ^v for coin orientation (like American coins).
