TOBIS Razor question

Hi. I'm new here. But I just bought a house and the guy that lived there passed awhile back. But he was a barber and as I was going through all his barber equipment that they left at the house I found a solingen razor. I haven't found it online or on here yet. But I was seeing if you guys knew anything about it. The only makings it has on it is TOBIS. It has a yellow handle and came in a box. It's nothing fancy like any of these on here. But I would like to know if it is worth anything. I'll try to get pictures of it later. I'm at work right now.

Thanks,
