PC advice on Golds.

1. Crippling Short bow of warding
Piercing dmg 12-20 Req 9 Marksman
Damage +14%
Energy -5
Lengthens Crippled duration on foes by 33%
Armor +7 vs elemental damage.

Not a great bow, Dmg is ok, req is not too high, Worth maybe 2k, but difficult to sell. But, then there is the +14% to damage unconditionally. Does that change the worth?

2. Ebon long sword of Swordsmanship
Earth dmg 10-14 req 7 swordsmanship
Damage +14% when health above 50%
Swordsmanship +1 (20% when using skill)

Salvage the Swordsmanship rune and merch?

3. Silencing Flatbow of Fortitude
Poercing dmg 12-20 Req 5 markman
Damage +19% while health below 50%
Lengthen dazed duration on foes by 33%
Health +29

Not max damage, mods iffy, Merch or sell really cheap?

I am trying to learn how to value the items on my own, so I was wondering If I am on the right track?

I am curious to why you see the damage mod as unconditional when it subtracts 5 en from your energy pool.

Merch all imo.........maybe salvage the silencing bowstring.........

Well if you would like to learn more about prices and certain tactics to push and pull items my advice to you would be to watch the market in some populated areas. As well, this forum is a great haven for learning the basics about prices in general and the basic deflation and possible inflation that items go through. Eventually one can predict these trends and capitalize on them. Whatever one does in GW, having a basic understanding of the market is always an advantage within the GW universe.

Like Hidden said, the first one isn't "unconditional;" the condition is -5 energy. As we learned a few days ago, calling that unconditional can get some people VERY upset for some reason.
Since none of the weapons is max damage, merch them all. Only extremely rare weapons are worth keeping if they're not max damage.
Also like Hidden said, watching trade spam in major cities, buying and selling a lot of items yourself, and checking these forums a few times a day, are the best ways to learn pricing.

When I first saw this post - 12-20 bows I thought wow, nice, max Presearing bows, especially that +14/-5 would be easy 100k++
...
then I read again, Golds... oh great, those may be among lowest dmg golds in game xD
feed the merch.
