うまい具合に力の入らない位置に穴があり、その穴も金塊がギリギリ通るくらいの大きさなので、かなりが握力ないと無理ですね。
まず金塊を縦に持つのが難関です。
ちなみにこの金塊、時価6200万円だそうです。

The hole's in a position where you can't put your strength into it properly, and the hole itself is just barely big enough for the ingot to pass through, so unless you've got a fair level of grip strength, it's impossible.

Firstly, just holding the ingot vertically is an obstacle.

Incidentally, I hear that this ingot's current market value is ¥62,000,000. Approximately $527,250 or €484,040.
