For the most recent Krause catalogue pricing - which will probably be adequate if you're selling them in Britain - you can check the NGC World Coin database.
Here is the Crocker & Hamilton, and
here is the Josephs. Use the EF pricing on the first one; "AU58" on an American slab converts to EF in British and Australian catalogues. I know the guy that supplies Krause's Australian token prices, and he definitely uses Australian grading standards.
I like the Josephs tokens; the depiction of the actual premises on the token is unusual in the Australian series, and they are the only ones to name the colony "Van Diemen's Land" rather than "Tasmania".
Was NGC able to grade the Josephs afterwards? Unless your "before" pic makes the coin look much worse than it really was, I'd be surprised if a coin with verdigris that bad could receive a formal grade, no matter how good the conservation job. Did you use NCS, or a local conservator?
