Since 'skin effect' is applicable at all frequencies except the very lowest - why not tell us what you really want to do and we can cut to the chase and recommend the use of Litz wire or the use of flat copper ... Classcically, I have seen silver-plated base metals being used in those RF circuits where resistive losses where to be minimized - including large, free standing tuned RF coils.
