Receiving 5 coins from the mailboxes in Fairy Garden. While I was playing, I opened 2 mailboxes, giving me 10 coins as an Innocent. However, I did not receive a One-Shot Bow in exchange of having 10 coins. I had to manually find the 10 coins in order to receive the bow instead.
Windows 10 Edition. Version 1.3.7.0
The image shows me searching these mailboxes, receiving my 10 total coins, but not receiving my One-Shot Bow until later on in the game.
