It's a pretty fun time waster
There are a few things that I can see that, in my mind, would get this a bit higher rating. 1) the music. It gets really annoying after about one time through the game. Maybe choosing a different coin would change the music. 2) there seems to be some "odditites" with the physics. Sometimes the coin shoots across the screen when it hits a peg and other times the coin seems to pass through the peg without hitting it. 3) the points the coin gets seems a bit odd. Sometimes the point is solidly covering 10,000 but the system thinks it's a 2000 score.
Other than those things, it is pretty fun.
