How to find code of of Chest named STEEL?

[BorutMaja]

My english is very bad but I find some hint how to find a code of chest nammed STEEL:

I think like that:
You convert letter S, T, E, E, L (STEEL) in numbers, s=19; t=20; e=5; l=12... so STEEL=19+20+5+5+12=61 ... Prize=750gold

Have I right? That I find with first Chest where I can unlock Chest (0-200) just with right nubers, named like tangletreeforest.

What you think about that?

There is only one chest with that kind of letters = numbers riddle, the one in that cave. Basically, you have it right. Any other chests like that one don't have that same kind of riddle.

Hope that answers your question.
