Sado-Nation Sado-Nation worth

The catalog shows that the Sado-Nation – Sado-Nation (Vinyl, 7") (Rock) is valued at $478.5 used [1]. For the other listed items—"Sado-Nation - Sado-Nation (Rock)," "Sado-Nation - Disruptive Pattern (Rock)," "Sado-Nation - We're Not Equal (Rock)," and "Sado-Nation - The Teal Project (Rock)"—the catalog did not provide a specific price. To get a better idea of their worth, I would need to search for them individually or check for similar items.
