Have you looked on the reverse side of the coin? Does it say 50c on the back? There were no US silver dollars minted from 1805 to 1835 inclusive.
This coin was struck in 2 varieties. Numismedia shows the retail price for a "normal" 1813 bust-type half at roughly $270. There was also an incorrectly engraved die that has the denomination "50c" cut over the letters "UNI" in "United States". This is classed as a mint error and might go for $400-$425.
You didn't say anything about the mint mark, so here's the range for conditions ranging from numismatic "Good", which actually means very worn, up to almost uncirculated. With no mint mark (Philadelphia) - retail is 15c in G, up to about .50. With a D mint mark (Denver) - 50c to . With an S (San Francisco) - 50c to .
