The prices I find have increased in recent years. However, my best advice is to wait until you get more replies here before doing anything with them. I collected around 75% of them in 2011 and paid an average of 20-30 bucks Australian, Only a few were pricey and got bid wars such as Pitfall II, HERO and one of the Dolphin patches. But as the market changes, so will The collectibles.
I collected about 75% of them around 7 years ago. Most then we’re average 20-35 bucks Australian. Then a few like Pitfall II had bid wars. Being a child of the 90’s and 00’s I only discovers the patches through Activision Anthology.
I was born in 1990 so I enjoyed them by not existing. Haha but the plus is these days I have an old set up with VCS and VCR. Wish I had a Betamax, too. It's weird to be nostalgic for a time I wasn't born. Sure I have fond memories of growing up in the 90's and early 2000's but almost everything I love from the 90's was aimed at teens and young adults which I discovered much later.
Too late for Atari to market that system. It's like releasing the Sega Genesis in a certain region the week the Nintendo 64 came out. Too late but cool variant. Exciting seeing anything Atari in Japan. A retro game store in Tokyo had a boxed Lynx but think it was an American import.
