Could be, but the mailbox is from a company in Mississippi, and it has a flag on the side, which I’ve been lead to believe is an American thing.
The letter also has a standard prepaid postage mark used in the USA (though I don’t know how that works in other countries)
It’s most likely not OPs and is just a repost.
Spoon’s [almost definitely] fine. Foil can do it though, especially crinkled up like that.
