Celtic Heroes

Im new to forum and having been playing just a few weeks and have noticed there is a huge gap in prices when people try to sell me stuff. I also have a collection of things id like to get rid of. so what is a fair price for things?
I especially want to know for
skill tomes and are any worth more than others?
rings
book pages and bindings
frags

theres a lot of other stuff but these are most common to me right now. or is there a price guide posted somewhere?

The prices vary for different worlds, frags also vary on costs like this:
Moon: i assume 500-1k (lowest of all frags)
sun: 2k-3k
oak: 4k-6k
crown: 7k-9k
elm: 10k-15k
drag: 20k-25k
As for the tomes, it depends on the buyer, people get really desperate when they create alts and they NEED the new tomes, so you're best off selling the tomes to them as you will gain the most money from it.
The rings go from different prices as follows:
minor: least price, like 1k
lesser: 2k
greater: 5k
grand: 6-7k (again, depends on how desperate people are)
and royal: i'd say 9k.
This info is off of my prior knowledge so don't judge me .
For the book pages, they go for 200 coins each and the bindings are normaly 2k for red (same with cover) and 3k-4k for blue (same with cover).
Hope this helped
