Hello, I would like to know how to decipher this

You mean how to decode it? Like this:

Code:

$ bitcoin-cli decoderawtransaction 01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0704ffff001d0104ffffffff0100f2052a0100000043410496b538e853519c726a2c91e61ec11600ae1390813a627c66fb8be7947be63c52da7589379515d4e0a604f8141781e62294721166bf621e73a82cbf2342c858eeac00000000

Download Bitcoin Core (https://bitcoincore.org/en/download/) if you haven't already.

What values, regarding what? Please be more specific. Ask the question like we're next to you.

You don't need to download Bitcoin Core just to decode a raw transaction. Plenty of tools to do it online, such as: https://live.blockcypher.com/btc/decodetx/

I think what OP is asking is what would change between this transaction and the coinbase transaction on the next block. Well, let's take a look. Here is the transaction OP has shared (coinbase transaction from block 1) with the coinbase transaction from block 2 directly below it:

Code:

01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0704ffff001d0104ffffffff0100f2052a0100000043410496b538e853519c726a2c91e61ec11600ae1390813a627c66fb8be7947be63c52da7589379515d4e0a604f8141781e62294721166bf621e73a82cbf2342c858eeac00000000
01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0704ffff001d010bffffffff0100f2052a010000004341047211a824f55b505228e4c3d5194c1fcfaa15a456abdf37f9b9d97a4040afc073dee6c89064984f03385237d92167c13e236446b417ab79a0fcae412ae3316b77ac00000000

And let's break it down.

01000000	Version
01	Number of inputs
000...000 (32 bytes)	TXID of the first input (in this case null data since it is a coinbase transaction)
ffffffff	Output index number (again irrelevant here due to being a coinbase transaction)
07	Size of ScriptSig - 7 bytes
04ffff001d0104	ScriptSig - could be any arbitrary data between 2 and 100 bytes
ffffffff	nSequence
01	Number of outputs
00f2052a01000000	Value of first output (this is 5000000000 sats (50 BTC) encoded in reverse byte order)
43	Size of script (67 bytes)
410...eeac	Script
00000000	nLocktime

So the only things which change are the input script (which doesn't matter since we are not unlocking any outputs in a coinbase transaction) and the output script, which changes the destination the coins are sent to.
