I have concerns with the modern cards from a long term perspective and it doesn't relate to the player. Anyone who collects Kelloggs 3D, 1970 Topps FB Super, early Topps Refractors, and many other UV and plastic 1990s cards is familiar with the deterioration of the base materials. Finding uncracked Kelloggs is becoming tougher and tougher as the plastic ages and contracts. Early refractors are already discoloring, in some cases inside high end slabs. 1990s cards with plastic coatings are sticking and curling due to the materials. And sharpie can fade. I doubt that this Trout card was made to archival standards. By the time Trout is inducted into the HOF his early cards may be showing physical deterioration.
Setting that aside, I too do not get the modern collecting mindset as respects 1/1 manufactured rarities, only because there will be a new, better manufactured rarity next year. I've even heard some modern collectors who do not consider this the best Trout card because it is a pre-rookie. Those collectors prefer the 2011 card.
