Why do you want silver plated?
I know all the marketing BS about silver plated wire must be good because it's more expensive but actually, it's only relevant in high frequency applications. As the frequency of the current flowing in the wire it tends to flow more towards the outside of the conductor (it's called skin effect if you want to go and look it up) and in THAT case then applying a lower resistance coating to the conductor (like silver plating for exampl) allows the highest frequencies to pass at a lower impedance.
AEGs run on DC. Silver plating is irrelevant.
