Swapping some silver (maple leafs) for credit swiss gold bar, have a question..

   
   Greetings precious metal enthusiasts!   I called some friends of mine who deal in jewelry and
   precious metals to ask if they would be willing to take some silver maple leafs in exchange for
   their credit swiss one oz. gold bar , they said ok.  My question is do the different years of issue
   of the maple leafs carry any additional value the way the American Eagle one oz. rounds do ?
   specifically between the series 1989 and series 2003 (silver one oz. Maple Leafs) . Thought it
    good to go into an exchange like this a bit better informed - so thank any and all who can
    assist here !    Argentium.

Bullion is Bullion! never pay above spot for gold and silver bullion coins and bars!. I have pre 1933 gold coins yes some of those are worth a premium as a collector coin but the ones you mentioned in your post are only bullion!.
