The Abraham Lincoln "Broken Column" medal by Charles Barber was originally struck in the late 1860s - it was created in memory of the assassinated president; versions were struck in silver and copper. Your medal appears to be a US Mint 20th Century re-strike of the medal, however. Market value for the re-strikes is typically in the $20 to $40 (USD) range, depending on condition.
