Hard to identify Coins and Tokens

Thank you for taking the time to look at this page. I'll update this page after I find out what these coins are.

Coin 5: Chinese Token?

I suspect the item below is a token. The obverse and reverse are the same and there isn't any obvious date. The design is similar to the reverse of the Wu Jiao coin Y#329 from the Peoples Republic of China, but the token has a simplified design and is significantly larger (25 mm verus 20 mm for the picture of Y#329 in my catalog). Please if you know why this token/coin was made and where it is used.

Previously identified coins

Coin number 1: Azores

The Obverse of this 24 mm copper or copper alloy coin clearly suggests Portugal, but the Reverse doesn't match anything in the Standard Catalog of World coins. I've searched Portugal and a bunch of countries that were colonies of Portugal. I also looked at the list of pattern coins and none seemed to match.

Andrew: Azores KM#16

This were in my mystery box for years until identified by "Andrew" after my post on rec.collecting.coins.

Coin number 2: Galata Bridge Token

I searched the Standard Catalog of World Coins many times and failed to find a picture that looks like this. I looked in the obvious countries (Morocco, Iran, Iraq, Turkey, Indian states, ...) and many more.

This is a copper or copper alloy coin 19 mm in diameter and thinner than a dime. The script is an eastern script I don't grok.

Andrew: a 20 para token used for the Galata bridge in Turkey

This were in my mystery box for years until identified by "Andrew" after my post on rec.collecting.coins.

Thank you for your help, Andrew.

Coins 3 and 4

These two 25 mm coins or tokens appear to be from the same issuer and denomination, but slightly different types. The most obvious difference is the size of the year. I looked through the Standard Catalog of World Coins but I can't find them.

Cheshire Cat: Pakistan KM#57.2
