It's possible that the [broken link removed] might be the most cost effective way to sell the shares. If consolidating the shares into fewer names might help reduce charges (not sure if it does) then you or your wife can transfer shares to each other with no CGT or stamp duty implications and possibly at no administrative cost.

See this thread as well on this issue.
