I decided to take my kids to the National Baseball Card Day event at South Bay Sports Cards (Sunnyvale, Calif.), where the shop — like many others across the country — was giving out packs to customers on this special day. What wound up happening was something that will never be forgotten.

This story doesn’t end with some card worth a small fortune. But it does end with smiles.

I told the kids about the day and how they were giving away packs at the shop to promote the hobby, a fantastic move by the way. Topps is the company with the exclusive Major League Baseball license so they are the makers of the cards given away on this day. Such events have been around for at least a decade, and have over the years included cards from other companies, including Fleer, which is now an Upper Deck brand.

My son’s comment: “I LOVE opening packs!”

For the record, neither of my kids have been completely bitten by the  card collecting bug.  I actually didn’t start collecting until I was 7, almost three decades ago, so it’s still early.  My daughter collects American Girl dolls and Shopkins. My son has learned the joy of opening packs from sharing in the ripping of my packs when I buy them, and his own Skylanders Battle Cast cards. Gotta start somewhere, I suppose.

So we went and along the way we started talking about baseball cards, and even some Olympic cards, which I had recently purchased from Target. I told them that we might buy some more at the store, it just depends on how much they were.

Personally, I didn’t “need” anything. But I’m always down to see my buddy at the card shop — for the record he wasn’t there today, which I didn’t know until we got there — and I wanted the kids to get their free packs. That was what this trip was really all about.

I checked out the stuff at the shop and decided on three baseball packs and then opted for a “blaster” box of Topps Olympics cards. These “blaster” boxes are the same as those sold at Target and Walmart, 8 packs for $19.99. I figured let’s have a little fun. The kids were talking about Gabby Douglas in the car anyway.

So I made the purchase and the guy at the shop — whom I do not know on any level other than being a repeat customer — grabs three random packs from his stash of Topps National Baseball Card Day packs, and then grabs three of the Kris Bryant cards — which appears to be the last card in the set — and puts the Bryant cards into magnetic holders for us, all free of charge.

Outside the shop I snap a quick selfie of the three of us in front of the store with our free packs. I wanted to tweet at Topps and subsequently enter the MLBPA Twitter contest for additional stuff.

My daughter grabbed a pack with Nolan Arenado on top, my son snatched up the one with Joe Mauer on top, which left me with Clayton Kershaw, which was the one i was hoping the kids would leave me. Kershaw is my favorite active player; he’s No. 2 all-time behind Roger Clemens on my list of favorites.

My son ripped his:

His cards: Joe Mauer, Ichiro, Sonny Gray, Josh Donaldson, Jose Bautista and Joe Abreu

My daughter then ripped hers and immediately says, “Oooh, Daddy!”

You see, during our conversation about Olympic cards in the car I was telling them about game-used cards — those containing pieces of shirts, uniforms, caps, etc., worn or used by players and athletes.  I also told them about autograph cards.

Out of the middle of her stack of six cards was one with ink. She spotted it instantly.

That’s injured Yankee Greg Bird’s autograph, serial numbered 062/165. The rest of her cards: Bryce Harper, David Price, Yadier Molina, Luis Severino and Nolan Arenado.

She was so pumped that I was super happy for her. It really didn’t really matter who the autograph was, but she was so surprised that she actually pulled an autograph.

“It’s like everything we talk about comes true,” she said.

My day was already made. The Kershaw card already made my pack a winner, but now I was curious if more ink would be found. There was none in mine, but it was a solid pack: Clayton Kershaw, Felix Hernandez, Zack Greinke, Salvador Perez, Andrew McCutchen and Francisco Lindor.

I purchased three loose Topps Chrome baseball packs in addition to the blaster.  Shiny, yet fairly uneventful.  I did pull the Kent Maeda rookie, which is a plus.

We decided to open the Olympics blaster box at home.  There was some discussion about doing a video, and we agreed to do it for fun but my phone ran out of memory. As we got through the first six packs, there was nothing of significance. We pulled three Aly Raisman cards — which my daughter liked — but still no Gabby Douglas.  And then it happened.

In pack seven, a base card of Gabby Douglas.

About two minutes before we got to Pack 8 I told the kids about the memorabilia cards in this product and how they were worn by the athletes and then cut and placed into the cards. I also explained how the cards were a little thicker than the others.

My son opens Pack 8, the last one in the box and says, “Dadddddddy!”

Boom.

Ryan Lochte memorabilia card.

“Oh my god, Daddy, it really is like everything we talk about comes true,” my daughter said again.

I realize these cards aren’t worth a fortune in terms of money, but the memories of how they were acquired are priceless. And before you start asking, neither the Bird autograph or Lochte memorabilia card are for trade. They belong to the kids.

This card adventure ranks right up there with the memory of my daughter’s first baseball game, which I wrote about here almost five years ago.
