At these prices the 1000 sat utxo is not likely to be a "real" utxo, but rather an utxo which was created for a non-monetary purpose, such as storing and transmitting arbitrary data.

That's apparently a usecase according to Core
Before making my first big transfer, I sent 2 tests of 10k sats each. I knew those would probably be non-spendable, but the big transfer was a big deal and I didn't want to lose anything.
Pretty good practice, Egg.
Good news though.. if they were regular transactions then they are spendable 😁.
They are regular transactions, but the fee to spend them would be bigger than the UTXO, I feel like. I don't fully understand how dust and UTXOs work yet.
