Top 25/50 rare steelbook list?

[Sirjump]

Does anyone know if there is a list of ie. top 25 or top 50 rare steelbooks (or limited editions)? Perhaps ranged by items printed or general rarity... Would this be too subjective or has someone tried to come up with something?

And would you rather separate the releases by country, by region or by other criteria?

1. John Rambo (Amazon.de, GER)
