Unless Mr. Vuijk dealt in coffee, it is likely a token that's good for coffee. The hole is presumably for easy collection and handling. The token pre-dates coffee machines. The metal and diameter are wrong, but common pre-1940. My best guess is that it was used like the Koolhoven token, whose use is described in the second paragraph
here.
As for the issuer, the shipyard looks like a pretty good guess to me. There are several coffee machine tokens for shipyards in this area. A member of a historical society for one of them told me how a coffee token cost 5 cents. That's a pre-1940 price, therefore an indication that coffee tokens were in use on the yards before coffee machines came about. A shipyard is a large and cold place. It makes sense to have someone go around with coffee regularly, rather than have the workers drift to the canteen and back to work again.
I may be over-speculating, but it seems that the single A on the other side is the result of the dot after the A landing on the wrong place. The engraver shrugged and started again on the other side. That sort of procedure sounds like the tokens were made in-house. A shipyard would have the metal (zinc was used a.o. for piping on board), machines and know-how to do that.
May I encourage you to add this token to WoT? Let me know if you need help.
