Due to the monster weight and past experience the best way I can deliver these with fast handling is by weighing out the quantity. I will weight this out to 5 boxes each 68 LBS copper pennies. Total weight 340 LBS. 

This listing maxes out the USPS weight limit for each of the max number of labels printable on any ebay per transaction (5 labels. 5 Medium Flat Rate Boxes, 70 LB max each)

It will fill 2, (5 Gallon) buckets to the top with a bit of room at the top of each bucket. each bucket would be 170 LBS with room for another 30 LBS

To help with the handling process I may split the 5 boxes over 2 days worth in mailing so you may receive them over the course of a couple days

Lightly searched, but you are still bound to find a bunch of wheat backs and other possible treasures that slip past my searchings. Canadian copper pennies possible as well.

Questions welcome

Thank you for looking,

Ryan
