Honestly, this thread is nonsensical. It is one thing to ask about gold in stock - but another thing to estimate a net worth. The value of items depends on what people are willing to pay.
(1) I would never pay 175 mil for a small soulforge. or 100 mil for a slither. For me, these items are worth about 80 for the forge and 70 for the slither.
(2) I would never pay bazillions for an ugly EM-deco-crap-item, just because it is rare. To me, items need to be useful. So, value of a jade-crap-statuette to me is exactly 0 gold pieces. Same for 99 % of all rares.
(3) The worth of stuff depends on the shard you are playing. Brainless folks pay bazillions for crap on Atlantic - you wouldnt get 10 % of the gold on Drachenfels, for exmample. No idea what my Luna house would be worth on ATL - but not much on my home shard DF. And: Who cares?
(4) 300+ Million for an etheral tiger? L O L
(5) 1.5 Billion for a castle? L O L
(6) 1 year ago, nice SSI-jewelry went up to 1 billion and more - now has landed much lower...
(7) Remember Luna Vendors with Luck Garbs for 90 and more millions? Where are we now? 45? L O L
Hence, you cannot estimate the net worth of something like pixels traded on different markets. Watch the auctions on the trade forums - there you can see that one day stuff sells for TONS of gold and another day, the same stuff sells for nearly nothing...
And in the end: Who cares! It may have a sense to discuss about how much gold you need to play this game nowadays in a way that enables you to keep up with others and to meet the requirements of new mobs. So, discussing gold values may make some sense. But this thread looks like "penis comparison" to me.
