Wow, Sally, this is some coin! There are two important cautions:
1. Counterfeits abound in today's coin market. Watch out!
2. Never clean a coin. Cleaning ruins value.
With those out of the way, your coin apparently is a pattern for the lovely US Flying Eagle Cent (view these at this CoinQuest appraisal page). A pattern coin is one produced as a prototype before the final design is selected and the coin is manufactured for circulation. A cadre of well-to-do collectors pursue US pattern coins. One must be well-to-do because these babies are expensive!. Look at the US Patterns web site and you will see the spectacular array of beautiful patterns available.
For your coin, the value will be several thousands of dollars, depending on condition and authenticity. CoinQuest thanks eBay seller pavo47 for use of their exquisite picture of this exquisite coin. Pavo47's coin sold for over $2500.
You should have your coin authenticated and graded by PCGS, NGC, ICG, or ANACS (do not use other services). If you need help with this, please write to CoinQuest or another site with knowledgable people.
