What is a good price.

I'm looking at a 1905 Early double ring set. It's in okay condition. What would be a good price for it? I don't want to pay too much for it. But it would be nice to have in my collection...

There was a mention of price in this thread

I'm not a collector so i could not tell you what is a good price, but i guess a good price would be what your comfortable paying.
