I think nobody will sell them for $.19 each, even in large lots.
better to swap for KM value then sell for .19 :)
I think .70$ for each is good price, as many of them are not so common as, for example US quarters, which you can easily grow from pocket change.
also, its depends on seller . I tried to sell them for 0.8$ in one FB group, and nobody bought. But another member, who puts coins everyday,and has a lot of customers sold them for $ 1,5 each , and in worse condition then my ones :)
