Some advice please?! We recently had an engagement family gathering in Europe and my generous grandad gave us 10000 euros in cash as a gift to help with wedding expenses and for a honey moon 😱 as much as it was so generous of him when we came back to the UK we realised there was a problem... as cash was in 500 euro notes which apparently have a lot of bad reputation which I had no idea about...after doing some research on google I understood why. so i am 'stuck' in the best possible way with 20 500 euro notes... depositing such large value of cash in my bank especially with foreign currency would probably be suspicious and I don't want to be treated as a criminal... my monthly income is 1.2 K after tax... post office and other exchange places I won't take it without a proof of origin like bank statement from my grandad account.... he says he been keeping that money in cash for 'Rainy day' for a long time and thought best to give it to his only granddaughter for her wedding... so there is no bank statement... what's the best way to go about it? May be keep it and spend in Europe but after reading not many places in Europe accept it either despite it being a perfectly legal tender. Even breaking it is not possible. Anybody has experience exchanging such a note? Depositing money into the bank in similar situation? Even thinking of next time we abroad blowing it all in a Gucci store and then getting a refund?! Please help
