Good question as it applies to all clad coins, including the copper clad penny.
As the found coin is legal tender, you should be able to get face value. I don't know if the US Government will back it's currency(s) and redeem worn/unsightly coins if turned in. If so, please tell me where as I have a bucket of zincos, aka stinken Lincolns (copper clad pennies) for them.
Even though the coins are legal tender, it has been my experience that many employees will not take them as payment at the cash register, even after cleaning.
Many treasure hunters feed their cleaned coins into a Coin Star Machine. Sometimes without cost if at a grocery store which will give them a credit to purchase groceries, some will credit your credit card.
Most likely, the Coin Star machine will deduct their cut, around a 10% processing fee. If you are willing to pay this high of a fee (what a rip off), you should do it periodically as it takes a lot of time to feed this no fun armless bandit.
