how is silver plated silver worth now
Any plated coins are only worth their melt value. Fortunately, as of early 2010 that comes to about $14 retail, or about $10 wholesale, for a 1921 Morgan dollar.
It's still worth about $4.50 for the silver, a 1965 is 40% silver but the plating adds nothing to the value unless someone wants it.
EPNS stands for electro plated nickel silver. It is a fancy way of saying silver plated. Items marked EPNS are not worth very much, but it depends on the item. A fork might only be worth a dollar or less, but a complete tea set could be worth $50-150.
There is no "series D silver dollar" (a coin) so I assume you're referring to a silver certificate. See the Related Question for more information.
If it's a copy, then it's not worth much of anything. It's probably silver-plated copper or zinc.
About six dollars
It's still worth about $36.00 just for the silver, the gold maybe 5 cents. The plating actually killed the collectible value of the coin.

Nothing, none were made. Your coin is plated. It would be "cents-less" to make a penny out of silver because it would be worth more than a dollar.
