Same numbers of heads

[bonanova]

Twenty coins lie on a table, with ten coins showing heads and the other ten showing tails. You are seated at the table, blindfolded and wearing gloves. You are tasked with creating two groups of coins, with each group showing the same numbers of heads (and tails) as the other group. You are only permitted to move or flip coins, and you are unable to determine their initial state. What's your plan?

Think this one has been posted before. 

EDIT: 

 

 

Divide the coins into 2 groups of 10.  One group has X heads and Y tails. The other has Y heads and X tails. Flip all the coins in one group.
