How do you get a silver shovel on animal crossing lets goto the city

First you go to the city after 8PM; and go to the place with 2 cones. (the right side) if the 2 cones are open and there is a light, go in. if it isn't open, try again. after you go in, there should be Resetti. talk to Resetti.

The second time you go there, there will be Resetti`s brother.

The silver shovel will let you get you more money when you hit your shovel on a rock.

Hope this helps.
Thanks.
