Its one of my favorite classic silver commemorative designs - congratulations on the purchase.
It would help to have additional lighting on the surfaces, the shadows make it difficult to assess the coin condition. The visible cut in Lee eyebrows holds the coin back from gem state, so I say at best MS64.
