Just tried it. Even to 2000, nothing changes with the balance. Also tried to find this exact address by using ismine(‘address’) and the answer in console was false
Which would mean the address is not part of that wallet and you don't have the private keys to spend the coins from it.
Did you ever import addresses or private keys to any wallets in all these years of using Bitcoin? If so, how, when, where, and where are the private keys?
Do you remember having addresses that start with different characters or do they all start with the same character? Legacy (1), Nested Segwit (3), Native Segwit (bc1).
