In the sentenced circled below "The 100 yen coin is found under the desk", It usesから to mark the location.
so this made me wonder "oh! if it's used like this, then certainly に should work to as it's also a location marker!" But when I looked for answers on "HiNative" they told me It's not natural, but when asked why they didn't know how to answer me. Here's the thread in question: https://hinative.com/en-US/questions/13891892
so Any information on this is greatly appreciated thanks!
