@chriscox2104,
Okay so you have to look and see if there is an artist signature. So you might have to open up the frame ( carefully ) sometimes the frame is done by the artist themselves. A lot of these pieces of art have a an entire history going back.
Some of these people were ex-military, to somebodies wives, or even children prodigies lost in time, to commissions done for etc reasons. Lost dreams, wants, hopes, outlook on life, etc.
So if you can research the artist firs that would be ideal.
Finding out who the original artist is
Finding out when it was made.
What kind of material was it made on
What kind of paint ( acylic, oil, water colors, etc ) was used.
That being said beyond that to get it appraised you need to go to a specialist.
