Here's my Jan 1986 SCD. Note the significant difference in $$$$ between the the real Mantle rookie (51B) and the his 2nd year card (52T). A factor of 5 to 1, which Mantle's
52T card's value has over his 51B card in this listing, has been (more or less) consistent since the 1980's.

......The $300 listed in this guide for Rose was really a "buy price" that most dealers were paying in the 1985-1986
timeframe. This card was so "hot" back then it was mind-boggling. Furthermore...."a rising tide lifts all ships"....was very apropo to describe the Rose card's affect on the rising
value of many other "rookie" cards of major BB Stars during the 1980's. It was a really great time to be in this hobby.
