　　I was really glad when your club invited me to share my coin collection. It's been my passion since I collected my first Lincoln cent in 1971; that's the current penny with Abraham Lincoln's image. Just a little history before I start in on my own collection. Lincoln pennies are made of copper, and they were the first United States coin to bear the likeness of a President. It was back in 1909 when the country was celebrating the centennial of Lincoln's birth in 1809 that the decision was made to redesign the one-cent piece in his honor. Before that, the penny had an American Indian head on it. The new penny was designed by artist Victor David Brenner. This is interesting because he put his initials V.D.B. on the reverse of the coin in its original design. There was a general uproar when the initials were discovered, and only a limited number of the coins were struck with the initials on them. Today a penny with the initials from the San Francisco Mint, called the 1909-SVDB, is worth over $500. Now, when I started my coin collection, I began with the penny for several reasons. There were a lot of them. Several hundred billion have been minted, and there were a lot of people collecting them, so I had plenty of people to trade with and talk to about my collection. Also, it was a coin I could afford to collect as a young teenager. In the twenty-five years since then, I have managed to acquire over 300 coins, some of them very rare. I'll be sharing with you today some of my rarer specimens, including the 1909-SVDB.

　　Today I want to talk to you about wasps and their nests. You'll recall that biologists divide species of wasps into two groups: solitary and social. Solitary wasps, as the name implies, do not live together with other wasps. In most species the male and female get together only to mate, and then the female does all the work of building the nest and providing food for the offspring by herself. Solitary wasps usually make nests in the ground and they separate the chambers for individual offspring with bits of grass, stone, or mud, whatever is handy. What about social wasps? They form a community and work together to build and maintain the nest. A nest begins in the spring when a fertile female, called the queen, builds the first few compartments of the nest and lays eggs. The first offspring are small females that cannot lay eggs. These females, called workers, then build a lot of new compartments, and the queen lays more eggs. They also care for the new offspring and defend the nest with their stingers. By the way, only female wasps have stingers. Most social wasps make nests of paper. The females produce the paper by chewing up plant fibers or old wood. They spread the paper in thin layers to make cells in which the queen lays her eggs. Most of you, I'm sure, have seen these nests suspended from trees. They may also be built underground in abandoned rodent burrows.
