In the antique world, its all about buyers,it does,nt matter how old, or how rare an item is...its all about desirability...the factors that you have to consider is,if you,ve paid a lot for this, then you have to recoup this amount + whatever profit you are looking for,but it does nt always work that way...because it is a buyers market,..if no one wants it,then its staying with you,this one you have seen at $525, how long has it been for sale,..if its in a shop then shops can wait for a buyer to come along,as its probably not eating any corn....by this i mean their not in a hurry, where as some people buy something to turn it over quickly, then find they can,t,and before they can buy again,they have to sell the item they,ve speculated on..is yours made of copper,or is it tin,....is the one at $525 made of copper,...post the link and let us see it,this forum is all about sharing..info,..we are not magicians,we don,t always find every site where an item is being sold,as for knowing more...well, you know more than us,..as for giving you a price range...until we see the other one,we can,t say,asd we have nothing to compare yours with,
