Can you solve the dark room coin riddle?

Watch the video to make sure my summary here is right: You are in a dark room with a pile of coins. The coins have a silver side and a gold side. You know two things about the coins. There are hundreds coins. 20 of the coins are silver side up and the rest are gold side up. It's your job to make two piles of coins that have the same number of silver side up coins. The room is in total darkness and each coin feels the same on both coins.

This video says there in "a surprisingly easy solution." I haven't solved it yet but I have a pile of nickels and I'm going to give it a try.
