Is it normal for newer penny rolls to have so much spotting on coins? Lately every roll I buy whether 2017-D or 16-D etc....has lots of spotting. Do I need another source or is this common? Any thoughts
The pennies are rolled by a third party vendor, who receives them in ballistic bags that weigh a couple of tons. There is no way of knowing what sort of protection from the elements that these bags receive before the coins are rolled and distributed.
I suspect oils and/or grease from the minting process and who knows how clean the rolling process is. I also suspect the SOP is 'Get them in, get them rolled and get them out.'
