LP2 Mint Boxes

erwindoc

I recently acquired a collection that had several unopened rolls of LP2 and LP4 mint boxes and several 09 Formative years bank rolls. What are the big dates for errors, so I can check the boxes. Are these better to crack open and search myself or liquidate somewhere else?

There's a huge mega thread about these that lists all the dates and times for the boxes that have the double dies. Can't find it by the search method though.
