How many Unown types are there in Pokemon Fire Red?

Answer 1

I believe that there are 26 unknown that look like letters, and 2 that look like punctuation.

Answer 2

There's 26, one for each letter of the alphabet.

Edit: There is not 30, there is only 26, one for each of the letters of the english alphabet, I know that there were some fakes, but I have a coin from nintendo that displays them all, its 26. There's a picture there and info.

Answer 3

The first answer is wrong! There is like 30, one for each letter in the alphabet and there is the comma, peroid, ? and the !.
