Peter has 10 different grading categories, five for smooth pipes, three for the blasted ones and two for rusticated pipes. The price range within a grade category is almost always constant (except for the (S) grades, of course), though some adornments can alter the price slightly.
|(S)||Smooth||Peter Heeschen's Highest Grade|
|A||Smooth||Better grain, less sand spots|
|(S)||Sandblast||Very best sandblasts; virgin sandblasts|
|A||Sandblast||More difficult shape, better blast|
|A||Rusticated||Rarely made recently|
