Would guess in the range of 50 to 100 dollars, not much worth unless in brilliant shape

I had a look but I couldn't find any prices on just the sails, anyone have an idea?

The issue with an older Mirror sail is that they used to be a gunter rig and now most of the new boats and racing boats have normal bermuda rigs and the mainsails are different.

If it's near new it might be worth $200 max but otherwise closer to $100.

There are still some guys racing with the gunter main but mainly at club level. Might be worth posting on a few WA clubs notice boards where Mirrors are sailed.
Try Claremont and Freshie in Perth and Princess Royal in Albany.
