Collection of tough population high-grade 1971 Topps hockey led by a Ken Dryden rookie graded PSA 9. There are three PSA 10’s in the collection, all of which are the only graded gem mint example of that card: #31 Williams, #73 Marshall, and #91 Berenson. Four PSA 9’s are in the collection, all of which are the highest graded example of that card: #11 White, #33 LaCroix, #52 Ecclestone, and #94 Pulford. Perfect lot for upgrading a high-end 1971 Topps hockey set.
