The Secret Super Battle (SSB) cards were awarded to the winners of the regional tournaments in Japan, and the card bought them entry to the finals in a secret location in Tokyo. There is also a set of Tropical Mega Battle (TMB) cards which were released in the same fashion, to winners of the Regionals. It was the younger age group who won the TMB ones. They are both very scarce, and very desirable, likely equally so.
The Pika trophies you mention were released in 1997 (Pokémon Card Game Official Tournament), 1997-1998 (Lizardon Mega Battle), and 1998 (Kamex Mega Battle) respectively (3 different sets). Although they’re colloquially (and incorrectly) known as the “1997” “1998” and “1999” sets. Again they were awarded to winners of the Regional tournaments in Japan. The Pika trophies are all highly sought after and valuable, especially in a full set from the same tournament. There may be a small premium for a 1997 copy, depending on the collector, although most would just want ANY Pika. With cards like this, it’s what someone is willing to pay (and someone is willing to sell for), so it’s challenging to assign objective metrics of value. They change hands infrequently, but a Lizardon Mega Battle No.1 just sold for 200K in a public deal.
Though “unique” by virtue of the winner’s name on the card, the 2000-2001 prints (from a number of different tournaments) are less sought after than all of the above cards. They do not have nearly the same caliber of art, they are non-holo, and they do not have quite the same lore. The art was used for a number of different tournaments from 2000-2002. They all look reasonably similar to each other, so they’re not viewed as being totally unique. Though there is also less sales data so it’s hard to really know. A winner is less likely to part with a card that has their name printed directly on it, especially a Japanese winner, culturally. The female ones are rarer, and more desirable.
There are some rarer and one-off type Trophies within this era which we have basically not seen sell, ever. I encourage you to use the Search function here and read older threads. Lots of goodies to be discovered, if you find these cards interesting.
Cheers,
