Identify varieties of Japanese "Kan'eitsūhō"

I have 3 of these coins, and 8 more of the new type.

Along with some 4 mon coins, and other types like reverse 文, 長, and 元.

Does anyone have any reading suggestions to help identify the subtypes of these coins? Or could someone with sufficient knowledge identify them for me?

I bought Hartill's book on Chinese coins month ago. I really enjoyed the content. I'm planning to buy this one on Japanese coins as a Christmas present for myself, hahaha. 

It's a shame that here in Brazil, you can only get these books by importing them, which is quite expensive. Do you have any other book recommendations? Or even a website?

If you want, I can take pictures of all of them here, just give me a few minutes to take photos, weigh and measure all of them.

My camera isn't very good, but I think it's enough. Here are the photos of the old types.

1st - 2,9 grams and 24mm

2nd - 4,2 grams and 24mm, this one is more yellow than the others.

3rd - 3,3g and 24mm

Here are the new types

4th - 3,2g and 23mm

5th - 1.9g and 23mm

6th - 3.3g and 23mm

7th- 3.1g and 25mm, this one is more brown than the others.

8h - 2.7g and 24mm, and also brownish.

Here are the others:

9th - reverse 文 BUN - 3.8mm and 25mm

10th - reverse 文 BUN - 3.6g and 25mm

11th - reverse 長 NAGA - 3.8g and and 23mm, slightly magnetic on half of it

12th - reverse 元 GEN - 2g and 22mm, slightly magnetic

13th - reverse  元 GEN - 2.1g and 22mm, very magnetic
