 LOCK_TIME 00000000

So the transaction is right, and the signature is assembled accurately. It additionally follows the “strict sig examine” guidelines. The tx is attempting to spend from mnAEswb3Aiz5YTsfCJc8vQETnSe19mc5Am to mnAEswb3Aiz5YTsfCJc8vQETnSe19mc5Am.
So I checked the signature towards the double hash of the tx (see the well-known pizza transaction run-through: How does the ECDSA verification algorithm work throughout transaction?):

The raw_tx.txt is:

0100000001e468833270cf713f3bbccc62b7b5b0fc0b0a4570608718530816795a6589f322000000008a473044022051646b77924f6bb7c411c5aa890110ab55db8812b8998fe24c8bdce39795ebd602200bc4de18fd5524ad8b946ee57604424e2b943ef2a14fc7199a7853dda0743cbe014104b97c679207532e0f4ee2515aedaba5f87700bbe0138f7457baa58e89a53153823ab29632e6c3c804ecaab5913656512339792479a1b898b7e5dc31f075ff8660ffffffff0176df1710000000001976a91448ddfd3891f3f422d5c3c9c25e35b382667fc6e688ac00000000

Eliminated sig, and entered your pubkey script into raw_tx_SIGHASH_ALL.txt:

0100000001e468833270cf713f3bbccc62b7b5b0fc0b0a4570608718530816795a6589f322000000001976a91448ddfd3891f3f422d5c3c9c25e35b382667fc6e688acffffffff0176df1710000000001976a91448ddfd3891f3f422d5c3c9c25e35b382667fc6e688ac0000000001000000

and double hash (the binary values, therefore some conversion first!)

  end result=$( cat raw_tx_SIGHASH_ALL.txt | sed 's/[[:xdigit:]]{2}/x&/g' )
  printf $end result > raw_tx.hex
  hexdump -C raw_tx.hex 
  openssl dgst -binary -sha256 <raw_tx.hex >ssha256.hex
  openssl dgst -binary -sha256 <ssha256.hex >dsha256.hex
  hexdump -C dsha256.hex 

So the dsha256 is in readable type:
6b37475a5388fb52f227817a0ddec00e7b69495b492cd7cdc6aff2afc44810e4

I take advantage of openssl to confirm the double hash hex file (dsha256.hex), with the signature and a “pem” key (must convert pubkey from hex to pem), I at all times get an error:

openssl pkeyutl -verify -pubin -inkey pubkey.pem -sigfile tmp_sig.hex -in dsha256.hex

whereas working via the pizza instance, it returns a “Signature Verified Efficiently”.
