It's called flipping (like people flip houses).
The OP may well have wanted the holed 1887 for some reason and flipped the one s/he didn't want. Or thought s/he saw an opportunity to make a buck splitting the lot.
But I think it's on the up&up - feedback from the original seller, EXOCOIN appears in the OPs history.
