The prices that appear in the above sections of the guide, are an estimate of the current value of each rare listed. They are here to give you Ball Park esitmate but can and in some situation will be WAY off due to what shard you play on, changes in Demand, (and in supply for spawning rares) and whatever the current market conditions are.
The best place to find the current gold value of a rare is to check www.tradespot.net and see what other rares or simaler rares have sold for on your shard.
The best place to get an idea of the cash value of a rare is at www.ebay.com
A final really good website is: http://www.uo-auction.com/
Please note:
1-There is nothing that "is standard" for pricing. If you really want a rare be ready to pay a lot more for it than the prices listed in the guide, and if your desperate for cash and need to make a quick sale your probobly going to have to sell for less. If you buy for more and sell for less than the prices listed your not being ripped off your adapting to the market and your needs, and the flipside is true, if you get more when selling, and buy for less than the prices listed your adapting to the current market conditions and your needs.
2-There is a MASSIVE diffrence from shard to shard for rares prices. Pacific probobly has the most runaway inflation of all the shards, and Great Lakes probobly has the least inflation. What might go for 500k on Great lakes in the same situation, and item on Pacific might go for as much as 1 million.
3-How rare an item is AND the demand for the item are the two biggest thing that determine its value. For example the marble table usualy sells for over 3 million for each peice, it was a server birth rare, but has spawned on numerous occasions on every shard since then. Not enough to say that it spawns steadily, but their are definatly more than 10 marble tables (that are legal) floating around on each shard.
Then take Pigs feet, a unquestionable server birth rare, only 2 spawned on each shard 1 for felucca and 1 for trammel, some shards only have 1 in curculation. Its Much Rarer than the marble table, but it generaly sells for the same or Less than the marble table. The diffrence is Demand.
