My dad recently showed me a little knick-knack he inherited a while back. I'm not sure if it was from his dad or his maternal uncle, but they were around the same age (born in the nineteen teens/twenties). It's a Liberty Head dollar coin and two dice in an acrylic casing. What is it? [more inside]

A coin flips three times and comes up heads 2/3. Not suspect.
But a coin flips 100,000 times and comes up heads 2 out of 3 times, that starts to look fishy. The standard probability of this is always roughly 50-50, but assuming a 2/3 ratio pointing to a "rigged" coin, how could you plot the increasing likelihood that a given coin is rigged? [more inside]

Of all coined currencies in histories, which in their day, or today (kinda two part question) were the most plentiful? Not used in transactions but just physically existed, minted minus lost.

Mystery token! What is it's use? What is it made of? When was it made? What do the numbers mean? What do the letters mean? What does the grid mean? What does the dial mean? What is the significance of AM? What does W. & H. CO. mean? [more inside]

The gold-coin contents of the cliche' pirate/dungeon treasure chest, how much would that be worth today? Assume a stereotypical treasure chest, knee high to an adult, filled with gold escudos in excellent condition. How much would the chest and contents sell for? Could you sell it?

While hiking with friends my daughter found a small box lodged in a hole in a cave wall...
Inside the box there was a small coin that looks quite old.
I took a picture of it with my phone but the quality is pretty bad...
I'm hoping that somewhere in the hive collective - there are some Coin Collectors or Numismatics that could identify it.
Attached is the link to the picture

Numismatists: what is this coin/token
thingy? It was found inside the wall of a late 18th/early 19th century rowhouse in the Seton Hill neighborhood of Baltimore.

Why do golfers sometimes place a token or coin behind the ball?
I know almost nothing about golf, but I've started watching it on a new HDTV as I find it beautiful to watch in Hi Def.
I just watched a player putt to within 5-6 feet. He put a token on the green right behind the ball, picked up the ball for a second, then replaced the ball where it was, removed the token and made the putt. What is the reason for this?

I have a coin collection that has sat untouched for 50-60 years. At the time they were collected the coins were taken from circulation. They are from all over the world (no U.S. coins) and were minted in the early part of the last century. They were mounted on light cardboard pages with scotch tape. As you can imaging the tape has gotten quite brittle and sticky by now and may have interacted with the metal in the coins. I need advice on cleaning and restoring the coins in my collection. I understand that under normal conditions collectible old coins should not be cleaned.

Is there a term for when you see something you like, later on consider going back to get it, and when you finally decide to buy it, it is no longer available? "Non-buyer's remorse"? Anyhow, I digress: [more inside]

I found a 1910 Indian head ten dollar gold coin in my childhood piggy bank. It looks like this
. I have seen it listed online for different values between $400 and $1700. I am broke and (regretfully) feel like I need to convert it into cash. How do I do this quickly, fairly, and for maximum profit?

Is there a word which describes a state where "importance" and "non-importance" happen at the same time? A word describing the unity of duality, the oneness of paradox, and "two sides of the same coin"?
