How to tell the Daily Stamp Rarity on Pokopia?

Question

you get a daily stamp, and the better the stamp, the more the reward, I think. My theory is the rarity of the stamp is indicated by the design, but I’d like confirmation on how to tell, along with the details of the rarities and odds, if possible. Whatever is known currently is fine

Answer 1

The rarity of the stamps are in fact determined by the design.

There are four tiers — Basic, Evolved, Legendary, and Mew. The titles are self-explanatory as far as designs go, with basic stamps having a basic / stage 1 Pokemon, evolved having a fully evolved Pokemon, legendary having a legendary Pokemon, and Mew having a Mew.

Basic stamps provide 50 Life Coins, Evolved 100, Legendary 200, and Mew 1000. If you manage to have all 5 stamps punched on your card, and additional 1500 Life Coins will be added to your total.

Unfortunately, it does not seem as though information is available on the probabilities regarding these stamps, as for the time being of course.
