@bazaaretw Let me start by saying that I agree with you in general. If I somehow would have gotten my hands on this cards years ago, and it now turned out to be authenticated and potentially worth a lot of money, I probably would sell it as well. Not to put into my house however (although I probably should tbh, haha), but to put into my Pikachu collection which I like more. Especially in today’s market, I could have quite a lot of uses for 50k+ USD. So in that regard, I do agree with you.
Having said that, what @fourthstartcg mentions above hits the nail on the head. You’ve only joined this forum in order to get this authenticated back in 2019 after you’ve found it, so you can sell it for as much money as possible. That has always been your goal ever since finding it. Sure, you may appreciate the history of it somewhat, but selling it for as much money as possible always has been and always will be your main goal with this card. Literally every comment you’ve made on this forum thus far has been focused around this card. You’re right I shouldn’t have said you don’t care about the history of the card at all. But you do care more about the money than the history or Pokémon. You even said it yourself:
And again, I never claimed there is anything wrong with that, or wanting to pay your bills. All I said is that I am sad as the author of this article that all existing copies are available for sale before the ink has even dried. I am sad money in general is currently such a huge aspect of this hobby, especially this year. I personally hate that, since I collect Pokémon cards for my enjoyment; for sharing it with other collectors who feel the same; for nostalgic feelings; for the chase; etc. But all this money, investing, scalpers, and :whatshouldibuy: talk is really tiring lately.
Anyway, I digest…
Also, some of the things you’ve just mentioned aren’t really accurate tbh:
A lottery ticket has no sentimental value. It’s one purpose is to be redeemed for money, and that’s basically it. Whereas a Pokémon card was made for kids; has connections to games and TV series; has nostalgia and possibly memories attached; has a history. For you this Blastoise card and a lottery ticket may be the same, but for us Pokémon collectors they couldn’t be further apart from one another.
Lol. That part about taking donations was a joke. Because you’re not active here on the forum you may not know, but I make articles like this reasonably often; help other members whenever I can; and have made 100+ Pokémon lists in my own time to help others and learn more myself in the process. That Efour Trophy for the 10th anniversary in my signature below was given to me for being the “most helpful Efour member” (not my words btw xD). I’ve never asked for any money in return when I helped someone, because I do it for myself and because I like helping others when I can. When someone asked me if they could donate to me, I simply said: “sure go ahead”. But I don’t ask for money, and am even hesitant to accept any money because I made these articles to help others and to share knowledge, not for personal gain. Also, FWIW, I haven’t received any donations yet, which I’m totally fine with.
Then by all means sell it. No one ever said the reasons you want to sell it were wrong. I think it’s admirable you want to sell it to pay off your depts. The problem here is how you’ve been trying to sell it, and how you’ve been commenting on this forum.
I am still grateful you’ve shared all that information back in 2019, because it resulted in uncovering this great piece of Pokémon history. But right now I don’t understand why you’re still on this forum? You said you don’t collect Pokémon, nor have any intention to. You also haven’t commented on any other thread in general.
Your card is a real test print; your card is authenticated by CGC; your card is now worth a lot of money. You’re in the process of selling it for a lot of money, so congrats and good luck with your shop in the future.
But because of all that I’m generously curious: if you don’t care too much about Pokémon (yes, this is just an assumption, but this is based on: 1) you said you don’t have any intention of collecting Pokémon; 2) you haven’t commented in any other thread besides your own or this article; 3) you’re trying to sell a piece of Pokémon history - regardless of what it is worth. So I’d say it’s a pretty reasonable assumption in that regard), nor are you too fond of most of the members here, why are you still here? I don’t mean this in a bullying or mean way. I’m just sincerely curious: why?
At this point, the card is real, and an actual test print, as you wanted. The card is worth a lot of money, and because of the pandemic and famous YouTubers, the current Pokémon market is as high as it’s ever been with new record sales on a weekly or sometimes daily basis, so an ideal market to sell in.
But based on the comments back and forth, it’s clear you don’t like our community. At this point, I also wouldn’t consider you a friend anytime soon either (even though I am grateful you’ve shared information back in 2019).
Just sell the card, and enjoy the easier life with the earned money. And good luck with your shop in the future. 
Greetz,
Quuador
