First up is 2015 Topps Heritage High Numbers. There is no difference design-wise from the standard release, but instead focuses on the younger talent. Not much variety photo-wise either, but Heritage has never really been used for the action shots. The Mets got a few insert cards that showcase their young pitching studs. Favorite card is probably Noah Syndergaard's rookie card. Biggest missed opportunity is not getting Alex Torres wearing his extra protective hat.
Next up is 2015 Topps Hi Tek. I do not believe that Brent had any team sets available for this, but it would be pretty hard to put one together considering how many different patterns the set utilizes. I kept it pretty simple here and picked up a few cards, a couple of "base" and one numbered Kevin Plawecki. No real opinion here. The cards look cool, but the various patterns make it difficult to collect.
Finally, 2015 Topps Update. Here we have the first Mets cards for a few players who debuted or were traded for during the 2015 season. Yoenis Cespedes, Juan Uribe, Kelly Johnson, and Tyler Clippard were all apart of the teams late season run into the postseason. Noah Syndergaard and Steven Matz both debuted in 2015 and helped get the Mets further and further through their playoff run. It is interesting to look back knowing that this team was the one that made it to the World Series that season.
The Mets were also given a near page full of inserts. This time the inserts show the Mets rich history of pitchers. From Tom Seaver to Dwight Gooden to Buddy Carlyle to Jacob deGrom.
I purchased nearly all of the 2016 releases from Series 2 onwards from Brent. I doubt I will get around to scanning those cards at this point. It would probably be best to start fresh for the 2017 releases.
