I haven't bought pennies from JMB but $65 for 5 pounds or $25 for 1 pound seems high cost.
5 lbs = 8.9ó / penny
1 lb = 17.1ó / penny
That seems high but I haven't bought pennies in years. I don't like it when retailers try to obscure the price by selling it by the pound. I doubt if you'd find anything good in it but I guess you never know.
Another thing I noticed is that the picture shows a cloth bag but the text says a plastic bag. Not a big deal but just mentioning it.
