The Spanish dollars which were used to create these were generally flattened prior to being restruck as Bank tokens. However, you can occasionally spot a few remnant details from the original coin. A Bank of England dollar where the original Spanish dollar date was still readable would attract a considerable premium.
On the OP's coin, there are a few traces of the original design visible: to the left of the date and around and amongst the letters of the word "England", there are remnants of the old Spanish lettering. However, there isn't enough surviving detail for me to ID the undertype coin.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
