The auction this year took around 1.3 million gold pieces out of circulation. There was at least one guy that still had 375K on him So there may be a bit of gold out there yet. With that said, I think gold is more like .03, and it has been that way for years. I haven't understood where the .025 came from. Now with it taking ~45K to make one item (2,3,5K to make relic, and then use relic and 25K + 15K/Ring to make legendary item), I think the demand/price will go up slightly. I know I don't have enough gold to make these pieces, especially in the quanity I'd like to have, and I still need enough gold to make the enhanced and exalted items. In order to have just one of each, you would need 140,580 gold.
3 relics x 40,000 = 120,000
1 enhanced x 80 gold = 80 gold
2 exhalted x 250 gold = 500 gold
2 relics x 5,000 gold = 10,000 gold (need one to keep and one to make a legendary item)
2 relics x 3,000 gold = 6,000 gold (need one to keep and one to make a legendary item)
2 relics x 2,000 gold = 4,000 gold (need one to keep and one to make a legendary item)
TOTAL - 155,580 gold
.....and I am sure that just one of each won't do for a party of 10.
