Pandale Dirt locality animals are collected from, or are produced from snakes collected from Pandale Dirt road in Texas. I heard that the Pandale Dirt road was a tire shredding and kidney crunching rocky dirt road that not many braved to collect alterna from back in the road cut collection days. Just not the most accessible or easiest area to hunt. This alone makes the local rarer in collections. I actually had a pair of Pandale Dirts about eight or so years ago. The male was so-so in coloration, and not super dark. The female was a gorgeous charcoal grey blairs with bright orange bands. Wheter or not this rarity makes them more valuable is stictly a supply and demand issue. I have NEVER seen Pandale Dirts advertised that I can remember, and have only seen Pandale Road (paved road) locality offered many years ago. The tricky part is having documentation that assures they are real-deal dirts. Remember, any one can call an alterna anything. Proving the locality is the hard part. I would say if you can verify the locality, a pair could be higher dollar in the alterna community.
