Slime appears in the community coin reference as an early progression option. A reported value is not a guarantee that it can be bought directly or rolled at a fixed probability.
What the evidence supports
Compare the coin you actually obtained
Open its details and compare the same earning label against your equipped item. Keep your level, accessories and temporary effects in mind. If you cannot isolate those conditions, treat the change as an observation rather than a universal multiplier.
Acquisition is a separate question
The official game supports rolling better coins, but this guide has no verified Slime drop rate or direct-purchase method. Read the current roll pool, currency and odds shown at the relevant prompt before committing resources.
When to upgrade
Assess how long you expect to use the coin and what else the material could improve. A temporary increase and a long-term investment are different decisions; neither requires chasing the most expensive item in a reference table.
Current numeric reference
See the shared coin table and its source for reported numbers. They are kept in one place so version-sensitive figures do not diverge across pages. No drop rate, resale value or in-game test is claimed here.

Reviewed against the cited public material. A review date is not an in-game test or a promise that a live game has not changed. Read the evidence policy.
