We have a collection of indian artifacts and antiques. Besides ebay, we want serious collectors only.?

I have a handicapped child and I’m learning a new stay at home business. Want to sell our collection online. Celts sell for $50. on ebay. They are worth hundreds. I’m sure that collectors buy them on ebay and sell them some where else. Where can we sell stuff like that and get what it worth without giving it away on ebay. I don’t mind there being a middle man, everyone needs to make a buck. But we worked hard for what we’ve collected. Somethings are too valuable to run the risk of giving it away. I know there is reserve pricing and such on ebay, but alot of expensive items sell very cheap on ebay. We know what we have is worth something, would like to buy on ebay and sell elsewhere latter on. But right now, would like to get a good price from serious collectors on what we currently have. New at online selling. Please help.
