Great Mauer! It's been on my radar. Hopefully I'll add one soon.
I've picked up this pair for the 9.5 collection this week. With Canseco I'm more a fan of the Donruss RC - and I'll probably pick one up eventually - but my focus right now is Topps RCs so I'm happy to add this 86 Traded. The Harper is a first for my PC, his 2012 Topps Update is the first Rookie Debut issue I've targeted for the collection. Harper has 4 base Topps RCs: the Rookie Debut, two variations from the factory set, and then a base SSSP that has been closing at crazy prices in high grade. Hopefully I'll snag a SSSP at a decent price one day, but for now I settled on the RD as it's his only flagship RC readily available from packs.
Good luck this month folks!
