Euro Coin Images 

Greetings. Does anyone know why so many euro coin images were deleted? I have high res images of all euro coins ever produced and those which will be produced in the future. I'm happy to upload new images, but I have a few questions on how to proceed:
 What licensing should be attached to the images?
 Where should I upload the images- commons or directly to Wikipedia?
 If to the commons, how do I do that and then how do I use those images?
Help is appreciated!
