This could be a private issue prewar. The more desirable VMs are the Govt issued numbered ones. There were also private issued replacement ones.
If this is a correct pre war private issue, maybe its worth 100 plus. There were also copies made like from Panasiuk. I can not tell if this is a private issue or a copy
sorry that is all the help I can say. Maybe you post on ebay and see what occurs?
