I love the "Black Swamp Find" provenance because you know the source, and the card wasn't altered. Folks who cross them over to SGC without the provenance are losing out big time on a future sale.
As I mentioned a few months ago, the Black Swamp Find made a significant appearance in the April 19 Heritage Auction. For those wondering whether the provenance of that collection still carries any cachet, consider the following:
A PSA 1.5 Jennings Red, horribly off-center, and with an actual tear in the border, sold for $1,560, because it was the only version of Jennings found in Black Swamp six years ago:

The same auction also featured a very clean PSA 5 Jennings Red, well-centered, with no tears, and it sold for just a tic above at $1,680:

Collectors are plainly paying for this provenance. Keep them in the BSF holders!
