This question mainly goes out to the Aussie collectors here. What do you think is a fair price for these. The glasses are in nearmint condition with only one slight mark on the lense. The box is obviously a bit faded/yellowed. I still have the receipt it has a purchase date of 23/03/91 So i think pretty good condition for their age. I have a spare nose piece to throw in as well as black trigger stems but one has a crack in it. Microfiber bag got thrown out a few years ago. I have someone locally who wants to look at them but just want a rough idea of what they might be worth in a trade.
