It depends on what condition it is in. The 1892 CC Morgan dollar is a very rare and hard to get coin so it is worth quite a bit. In poor condition (G-4) its worth about $220. In good condition (XF-40) its worth about $500 to $600 and in almost new condition its worth about $1,700 to $2,500 depending on the luster of the coin. If its in absolutely flawless condition with maybe only one or two scratches and looks brand new it could fetch as much as $50,000 to $80,000. I would recommend you get it certified by this company: anacs.com and sell it via the internet this will get you the most money in the long run. If you don't want to get it certified then your only option would be to either sell it at an auction or to a coin dealer since most collectors will not buy rare coins on the internet unless they are certified.
