Union Pacific Railroad Silverware

I recently purchased a set of 80 forks, knives, spoons, and eight large serving spoons.  This silverware has the stamp "UPRR" on the back of the utensils.  Most of them are written in cursive, while a few are stamped in print.  The silverware needs to be polished, obviously.  But I"m wondering what something like this is worth? 

There is also a stamp that reads, "Victor and co A1 + overlay" and then a unique number on the utensils.  If anyone has any information about time period, value, etc. I would love to learn more! 

It also came in a wonderful, antique wooden silverware box from Thailand.  Very neat! 

I spent fifty dollars for the eighty piece collection plus the box, I'm assuming this was a good investment? Fingers crossed! :)
