I'd say around $15 (poor condition) to around $30 (near mint state) and $50 (high grade mint state). They are some of the more common commemorates and were made in bulk.
Somewhere in between about $100 and $500

Please check your coin again and post a new, separate question. There were no "exposition half dollars" minted in 1883. If you're referring to a Columbian Exposition half, these were minted in 1892 and 1893; there's more information at the Related Question.
The Columbus half dollar was a commemorative coin celebrating the 400th anniversary of CC which took place in Chicago. It is also known as the Columbian exposition half dollar. This price varies from $200 to $650 in uncirculated grades to priceless (well over $10,000) in top proof grade where only 400 specimens were produced.
It is worth about one dollar.

A "one dollar" coin has the value of one dollar!
