Always better to look at completed sales - I can see 11 - prices seem to hover around mid to high 200, with original shade obviously increasing the price. Then some colour variations may be rarer (and more valuable) than others. Condition (like earrings, diamantes) is obviously important, also working condition. Prices? The flooding of the market with repros has inevitably damaged the price - the people who just want the look don't care whether it's an original or not, while those who do care may be hesitant to buy. I am not an expert on Barsony but you do see an awful lot of it around these days.
