Collision with Coins

I'm working on a poem about Audrey Munson, an artist's model from the early 20th century with a tragic story. Among many other things you very well might have seen, she posed for two different US coins, as the face on  Mercury Dime and the figure on the Walking Liberty Half Dollar.

My younger son is a coin collector, so I asked him if he had either coin, and he said he didn't think so. "Can you check anyway?" I asked him, knowing that since we live in Japan, his US coin collection is less robust than some of his stashes from closer countries.

But he checked, and he did in fact have a Mercury Dime. And I held Audrey Munson's likeness in my hand, and my son and I marveled as our passions collided.
