In Europe you'd get $250-$260 for the mouse & ox alone plus about $150ish for the rest. So around $400 give or take $20
There is one dealer in Germany who is selling 1/2 ox for 52 EUR. Does it mean that 1/2 mouse cost close to $200 ??
That's one dealer which is roughly $75AUD like anyone if he has bought at a reasonable price and wants to offload quickly he will, they usually go for around 80 AUD, mouse around $120 AUD Just done a check up and prices for mouse & ox are less than I thought at the moment ox around $70-80 mouse around $100-120. So around $350 for the lot Like anything on ebay you can pay more or less.
on ebay recently, I have seen around 4-6 listings for the ox. When I was searching for one to complete my set about a year and a half ago, I couldn't find one for three months. Go figure lol. I know the mouse is the "key date", but they seem to be more plentiful than the ox.
