I'll say at least 60% of the gold on here came from true UO acts I say this meaning hunting and other things that go along with it, the other 40% came from the long line of donating to the server and all the other unnamed things such as when Craig was a gm and created billions of gold that the server thinks is gone. All of this is product of hybrid being around for so long and having so many rares introduced to the shard, there are probably more 1 of a kinds in this whole shard then there are of one of each multiple item added (like kitchen sandals Pw robes etc.) probably doesn't make sense because I'm working and typing this at same time but you get the pictureone word: POKER
just like in real life, 99% of the gold on the server is pretty much always in the control of about 1% of the servers players..
it just shifts back and forth between them from poker wins/losses and the high end rare market, mostly poker tho..
when some of these guys loose big, hundreds of mil they look for sellers to buy back in and try and win their money back, then when they win big, they become the sellers in alot of cases
in terms of overall gold, the net gold amount on the server should actually be going down day by day as you cannot buy gold from the store anymore and as people purchase things from npcs, dropped/decayed gold, stuff like that
