No, that the coinbase transaction (not the exhange) of the block that you've mined.
Since it has status of "0/unconfirmed, not in memory pool", your node doesn't have that block where it's included.
Broadcasting the block (if you still has it) is no good either since there are already 14 years worth of blocks built on top of it.

If you decided to rescan your blockchain (in case it's missed during IBD),
You can do it fast by rescanning only the old block heights where it should be included.
Use: rescanblockchain 0 33000 to scan only blocks from 2009,
replace "33000" if you want to scan more beyond your projected date, but it'll be slower.
