NO that can be trackable those are hard to sell them to a private party 100 is the max I stack I would never keep those if I was you I would have them melted into rounds. I enjoy doing my own pours 2oz 10 oz odd weights etc not sure if you are set up to do that. I just buy 100 oz bars because I can get them at spot or less I went back in the silver market when silver was around $13.69 in 2015 have not bought since. if the guy you sold the 100oz stackable wants more let me know that is an outstanding price you sold them for you did well
