Anyone know a place to sell collectible putters?

Other than EBay, are there any particular sites that specialize in rare putters? I have a Dalehead Anser with Karsten co. in the cavity and a new but collectible Anser 4ti. Seems any regular sites there is no interest. Thx.

I have no idea about putter-specific sites. There is the sales section on this site here, and there is a U.S. based golf club sales group on facebook, facebook also has a UK based golf sales group as well. Sometimes a local craigslist posting will generate interest.

edit: I just tried a Bing search and several options showed up for Ping putters collectors sites.
