All of our change goes on to the top of a “battery” “piggy bank” ..
Youngest grandchild - used to be youngest child in the house! - has the “chore” of charging the battery by feeding it coins. One by one. So the twins argue (gently) about whose turn it is to do their chores each time they come over. 8<)
Have about 5-8 lbs of coins in it now. We periodically empty half of it to the real bank when they are not around.
At my house, the person who is willing to roll the coins gets the value in useful currency. However, more commonly they just fish the quarters out when I’m not looking, leaving a jar largely filled with pennies.
