What is the value of a 1933 silver eagle coin copy?

The date and Word "copy" strongly suggest your coin has very little intrinsic value, and no value as a collectible. The only exception would be if it contained any silver, which should be indicated somewhere in the design - e.g. "1/2 oz 999 silver" or similar Wording.

To explain:

• Silver eagles are modern bullion coins made since 1986. They're not intended for spending.
• The only coins made in 1933 that were called eagles were $10 gold pieces; most of those were withdrawn and melted.
• In collecting, a copy of any article is almost always worth far less than the genuine item.
