Please help if this an antique etching or a print

Please help with artwork Giovanni Battista Piranesi (Italian, 1720-1778). I am not sure if it is a real etching by this artist or a reproduction in a much later date.
I searched online and I can see several that sell for a good amount of money.
This artwork is called: Veduta del Palazzo fabbricato sul Quirinale per le Segreterie de Brevi et della Sacra Consulta
Approx. Dimensions:
Etching/Engraving plate: 400 mm x 622 mm - (15 3/4" H x 24 1/2" W)
Sheet : 508 mm x 724 mm (20" H x 28 1/2" W)
The plate has a number 38 in the lower right corner. I seen few that didn't have that number like at the following URL: https://www.karlundfaber.de/en/prod...abbricato-sul-quirinale-per-le-segreterie-de/
Under 10x loupe, it doesn't look like a modern reproduction as i don't see the dots. But, also don't see the groves on the edges (not sure what they are called) of a pressed etch.
Greatly appreciate any help. Thanks in advance

As you say yours has the number 38 on bottom right hand side, whereas Rinks Dorotheum example doesn’t.

 

The grooves or indentations are called plate marks, FYI.

 

Is there a center fold? Can you tell if it's printed on laid paper?

The plates were printed in different editions over time, but I do not have specific information. This could be a re-strike from a later edition.

 

After further research, I found online an ebook at https://play.google.com/store/books/details?id=Al1NAQAAMAAJ&rdid=book-Al1NAQAAMAAJ&rdot=1
*** The name of the book:
Giovanni Battista Piranesi: A Critical Study, with a List of His Published Works and Detailed Catalogues of the Prisons and the Views of Rome

My etching is from the Views of Rome

On Page 25:

It says Number 38 lower r. margin

So it looks like this print etching is from this book.

I added a comment that I opened the frame and that the paper is a bit thick but still can see the outine of the work from the back. It seems like woodblock, the ink will get in the paper and can be seen from the back of the print
The lines are crisp and only black and white colors seen. No grey colors.
I can feel with my finger the plate mark at the edges. Under the loupe, no dot matrix but clear line.

 

It also associates the number with the 1st Paris edition.

It will be an etching, not a woodblock.

If it's laid paper, hold it to the light and you should see lines like these:

 

Good work!
