Just curious. Makes no important difference. They are what they are.

When I saw two dates my mind went to "reorder". I then thought, ok, if they reordered both denominations, either they got busier and needed more chips because maybe Archie was there harvesting.

Then i thought, well maybe they started with one denomination and then decided to add another.

I'm also one of those crazy types of people that marks dates for the chips into my database as well as datase of operation.
