Antique Chinese Chest with Artwork

I found this gem in my grandparents storage, and they would like me to find more information on it. They don't remember where they got it, but it appears to be very old. Made of wicker and wood, with artwork on the top and some metallic details as shown. It's also about 2 feet tall I guess. I talked to my Chinese friend and the artwork appears to be a picture of a Buddhist God named ???? or Amitabha. I would really like a rough estimate on how much its worth or how old it is. Thanks!
