Coins for School Kids

I collect world coins in order to give presentations to elementary, middle & high school classes on the topic of Coins & Countries. I give out packets of 10 coins from the 6 continents to each student so that they have a coin from each part of the world. I discuss currency, culture and location as part of a Social Studies segment of education. I am a retired professor of Criminology who still likes to teach. If anyone has "extra" coins they you like to donate to this cause please email me at profpuzzle@msn.com Dave Agresti
