If you have a shiny coin, the scattering of the light (diffuse reflectance, not specular reflectance) can make the coin "seen" at a distance much further than the eyes (or camera) can actually resolve the shape. Try the same thing with a dull coin, I think you'll find different results.
I like the 2 hits in 10 shots idea, but once you get out to the max distance, then how do you rank higher?
Yes it is true, if the coin was tarnished and not shiny, the visible range would likely be a lot less. On the other side of the coin (pardon the pun), If the sky was clear and the sun was at my back, a shiny coin would be visible from a very long distance away.
Regarding the ranking system, I don't think a "max range" may be necessary, and perhaps the system made difficult enough so anything over 50m (5 stars) is very rare.
That's why I've been thinking 3 hits in a dozen shots is probably better than 2 two hits in 10. Would be more interesting and exciting to watch, as well as make it suitably more challenging.
