We have found almost all of the state quarters, and now we are filling our book of America the Beautiful quarters. I'll take a look at these lesson plans from the US mint. There are also lesson plans for the $1 coins.
I was disappointed to find out that the presidential coin series had been suspended, but I was glad to discover that the remaining coins (from President Arthur onward) will still be produced. They will only be available for collectors. The number of coins minted for each president is down to less than 10 million (as opposed to almost 100 million for Lincoln and over 300 million for Washington). They can be purchased in rolls or bags from the US Mint for about 10% over face value.
