Ok i like that but can i try a offer a few Tweak suggestions..

Change the coin from Silver to Gold. (Gold tends to make it pop)
Change the gold intertior (grooves,etc) to Silver (cos the current design kinda washes out the other colors.
Switch the "O" with a LOTTO 8 ball.. (Not really necessary)
Oh and leave the "LOT" as silver..
Oh and maybe a shade darker on the multi-colors on the inside of the coin.. current coloring looks a little flat.

I loved the button and the image above the button..
