Sentinel 319 PM Replacement Case

I have had this NOS Sentinal 319PM Case since the early 1970s when we helped with a friends Grandmother's estate. Is there any value to it, or would it be good to try to sell as-is to a person looking for a case? Or, should I look for a Sentinel radio with a damaged case to use this to keep for our growing radio collection? Any thoughts would be helpful. Thanks
