Our beloved Liberty Bell appears on several US coins, including Franklin and Kennedy half dollars, and Eisenhower silver dollars. But it appears on the reverse 'tails' side of the coin, not the obverse 'heads' side.
The Liberty Bell theme appears on many different tokens and medals, including the one in our picture and several others, as well as in jewelry.
We have not been able to find our requester's piece, dated 1837, so it must be somewhat rare, so its value is probably a little higher than most of these common medals. However, its sad appearance, noted by the 'repulsive' evaluation of eye appeal, will render it essentially valueless.
Most Liberty Bell medallions are made of non-precious metal and their price depends on condition:
COMMON VARIETIES, AS SHOWN ON THIS PAGE

If you can find one made of precious metal like gold or silver, Liberty Bell medallions are worth their weight in the precious metal. Use Kitco.com to find the current value of gold and silver.
