I answered you from work. I am now at home.
I had an Alaskan chippers web site bookmarked but the link does not work at this time.
He had the 49'ER chips on his site attributed to an Alaska game runner.(moving gambling operation). He had a good story with them and the years of operation and the name of the operator if I remember correctly.
I have the $5 & $25 49'er. Same font. I have them listed as LV. I think the Alaska attributation put them in doubt.

To answer your question, the old distributors had no problem issuing duplicate chips even though the boxes said non-duplicate. I have a number of Mason file cards with the exact same chip sent to 5 and 6 different names and different parts of the US.

I have sent this link to Jimbo. He knows as much about downtown as anyone. Geeez, that hurt me to say that. <g>
