#1 is an ordinary cent that's been plated, and had a Masonic symbol stamped on it. Objects known as "Masonic pennies" are used in certain Lodge rituals; some Lodges (presumably the richer ones) purchase specially made tokens for this purpose, other lodges presumably use a counterstamped, plated cent.
#2 is indeed Asian; more specifically, it's from China, during the reign of the Qian Long Emperor (1735-1796 AD). Due to the long reign and relative prosperity of the Chinese Empire during this time, this type of coin is extremely common.
#3 is what is known as a "love token" - an ordinary coin that's had one side filed flat, and initials carved into it - intended as a memento or keepsake from someone to a loved one, often because they've been separated by distance. To some collectors they're interesting historical artifacts, to others they're just damaged coins.
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
