Congratulations to nprofile1qqsvqses4kkaj5yvrtgudm0q4m2ajg4rv4czrym7yp26srqm9pjueacpp4mhxue69uhkummn9ekx7mq8zkrsf for solving the puzzle! Behold the answer:

A: The archaeologist returns one gold coin to the chest after reading the note, as they had initially taken three coins. Leaving the key (the third coin) adheres to the 'none for the greedy' phrase. Now there are five coins in the chest - two from before and the three returned.
