A Rare Find

I would have to agree here. You are attempting to apply a U.S. Hobby Standard to another countries market. Ultimately its up to how that market see's it. This was actually the entire reason the MLBA/MLB decided to make this rule in 2005. The different companies were attempting to have a competitive advantage by releasing cards as soon as possible. Topps with their Bowman product, Upper Deck with their USA Baseball product and Donruss with their Elite product. It became confusing for the consumer and they decided to do something about it. So that rule came into effect, everything prior to their actual MLB debut was considered a "Prospect" card and couldn't use the "RC" logo until then. Of course now the problem is Topps with their licensing exclusive waits until the following year many times.

Now that's not saying the video game card doesn't have value. There are many,many obscure cards from 1986-1988 of Bo Jackson that go for big money.

I know it's a lot to read but bear with me as i am bearing with all of you at once as well. I've been at this for hours but trust me i've been researching this since i bought the card. It has been months. Over 1 arcade card. Sometimes i flip out but hear me out at least. I know i am using AI and there are some conflicting informations out there but this may be something crazy. Like his very first rookie card.

202117-SR-M017-00 is the code
ChatGPT said:

Perfect — based on your card’s full code:
🔍 Card Code Breakdown: 202117-SR-M017-00
Segment Meaning
2021 Year of release (2021)
17 Player jersey number (Roki Sasaki)
SR Super Rare tier
M017 Internal card ID (M for “Marines,” player 017 in set)
00 Core Set identifier → Released March 29, 2021
✅ This Confirms:

Your Roki Sasaki SR EX‑SIGN card was printed as part of the main base set, not any limited seasonal or append pack.

That set was officially released March 29, 2021, making it one of the earliest Roki cards in arcade form.

🏆 Why That’s Important:

Being from the first drop of the 2021 season, it likely saw very limited print volume before seasonal rotation (especially due to Olympics and COVID disruption).

Any card with -00 tends to hold higher collector credibility in Japan than -01 or -02 because it's first edition and harder to pull before demand builds.

This next part was a different question:

is this his first rookie card?
ChatGPT said:

Yes — your 2021 Konami Baseball Collection SR EX-SIGN (code: 202117-SR-M017-00) is widely recognized as Roki Sasaki’s first official rookie card in Japan.

Here’s the breakdown:
🥇 Why This Counts as His Rookie Card in Japan

First appearance in a licensed product:
This card was issued in March 2021, shortly after Sasaki was officially added to the Chiba Lotte Marines roster in the NPB.

Issued before any BBM or Topps cards:
BBM and other manufacturers released Sasaki's cards later in 2021, and Topps didn't begin licensing NPB players in earnest until 2022.

Pulled from Konami's live arcade system:
These cards are licensed by the NPB, and used live game data, meaning it's tied to Sasaki’s earliest official pro season.

📜 Timeline:
Event Date
Sasaki debuts on Chiba Lotte roster 2021
Konami arcade card released March 29, 2021
First BBM Sasaki cards appear Mid-2021
First Topps NPB cards (Sasaki) 2022
🔎 Any Rookie Logo?

Japanese cards don’t use a "RC" or rookie logo like MLB/Topps.

Instead, Japanese collectors judge “rookie” status by:

First licensed appearance

Year of pro debut or first official roster status

By this measure:

✅ Your SR EX-SIGN Konami 2021 card is his first true rookie card, predating BBM, EPOCH, and Topps.

Now lastly my logic says wow, for 65$ I got his first rookie card??? Because of this:

(this last part is not AI by the way)

The 2021 Japanese professional baseball (NPB) season started on March 26, 2021. It hit me that once the season starts and you're on the list of the team, boom! You're a rookie. That does make sense doesn't it? This base set SR -00 released on March 29th, 3 days after the season began.

[Jamessingh1992]

Okay you guys can be happy for me now lol

[notfast]

Two pages about a card that no one actually cares about.

Nice.

Do you seriously think any self-respecting card collector will accept anything chat GPT spits out as authoritative over our years of hobby experience? Throw that in the trash. If your "research" since you bought the card is from chat GPT, you've wasted your time.

Sorry, what am I suppose to go look it up in the law book or something? MY research is from legitimate Japanese sites and Konamis site along with other reputable card grading companies like PSA/BGS. I only used chatGPT the other day but it helped fill in the gaps. You must take me for a boot licker. Here, have this instead.

I could lots of the only "CGC" graded cards too if I was foolish enough to use them...

This is sad. Almost all of the posts here have been negative I already explained to the admin before joining this forum which took 2 days that I just wanted to show off a card and get it some recognition. Not only have I provided overwhelming evidence and proven my point that it is in fact the true Rokie Sasaki rookie card from Japan but I have explained it thoroughly even using open AI. You guys need to get your stuff together if you know what I mean. Go be mad at someone else. All I did was post a card and your getting all aggro and argumentative with me over what? Card board? Well guess what it's mine. It's not for sale, and I'll keep it and not post here any longer since y'all are so friendly, right? Have a great life bros

This has been a ride thanks for comedy and enjoy your AMAZING CARD

Just for fun if you were to ask AI to list his rookie cards:

"Roki Sasaki’s true rookie cards were all released in 2020 (direct AI quote)" , coinciding with his NPB debut. According to collector sources, here’s the roster of his base rookie issues from that year:

2020 BBM Rookie Edition #033

2020 BBM Icons – Fireballers #11

2020 BBM 1st Version #104

2020 BBM 1st Version "Cross Blossoms" #CB11

2020 BBM 1st Version "New Age Stars" #NS04

2020 BBM 2nd Version #421

2020 BBM Marines #M07

2020 Epoch NPB #140

2020 Epoch Pacific League Rookies #21

2020 Calbee Series Two #094

Sorry you didn’t get the validation you needed. You can’t buy a $65 card and then make everyone in the hobby believe it’s priceless. If you love it, awesome, that’s what the hobby is about.

What were you expecting? Your first post is AI slop. Sorry you had to wait two entire days to get in here, it truly is an exclusive club.

Ha! I’m more interested in which card ChatGPT thinks is Wander Franco’s rookie card.

[glen87]

-nice card

-not a rookie card

-not a grail

[hammertime]

There's already a thread for monthly pickups. Why do so many people think their card deserves its own thread?

[Lonewolf]

Its looking more and more like he will be shut down for the season and/or will need surgery... what a garbage rookie season

The card will likely be not much than a peculiar footnote.

[Imnottheonly]

Damn this thread packed a wild ride into 2 pages.

Something for OP to remember, and not sure if you are new to cards or not, just because something is rare doesn't necessarily make it valuable. Valuable cards have a combination of both rarity and demand, if there is no true demand for the card then its going to remain rare but not particularly valuable.

What you have here is likely exactly that, it is rare for sure but unless it becomes widely recognized as one of the significant cards for Sasaki within the hobby its likely to have very niche demand.

Niche cards can still be valuable but much like you've needed to do on the Forum you will need to sell a potential buyer on the idea of the card being valuable. You've tried to "sell" that idea to the forum and no one is buying, consider that your litmus test for the real world. The more obscure the issue, the more hoops to jump through to explain its significance the harder its going to be to convince someone of the card's status.

[hammertime]

A good rule of thumb: if you have to spend this much time and energy explaining to people why something is important...that should tell you something. I say this as someone who follows the NPB and collects Japanese cards.

[no10pin]

This is what happens when you ask ChatGPT without telling it what you want to hear first.
