2c Puerto Rico... Is This A Precancel?

I have a plate full of these 2c, and I noticed one (arrow) that
has 2 cancels. Diagonally it says 'Puerto Rico', and that one
is a little too nice, it is centered fairly well, and doesn't
leave the stamp.

Then the other are the horizontal lines that tied it to cover.

They certainly appear to be 2 different cancels, and possibly
a pre-cancel. Thoughts?

Thanks!

Not a precancel, just an overprint on what looks like a SC#251, making it a Puerto Rico SC#211. Indicating use in Puerto Rico after it was ceded to the US after the Spanish American War 1898

My mistake. Looking at the spelling of PUERTO makes it a SC#216. The 211 was spelled PORTO

Is that a "PORTO RICO" or "PUERTO RICO" overprint? If the former, it would be a #211; if the latter, it would be a #216. I think it's a #216, which according to my 2002 US Specialized Catalog, would carry a used value of $2 (may have changed a bit since then, though).

It's a "U", but it's funny looking.
It's not in the same font as the rest of the letters.

It appears as though it is a "U" that is fashioned from an "O".

I guess they found their typo, and instead of making a whole new
"Puerto Rico", they just modified the "O" to a "U", and let it eat.

It is indeed Scott 216. Initially US stamps were overprinted PORTO RICO, after the island was invaded in 1898. It is the anglicised form of the name of the island. Scott 216 is the corrected name overprinted PUERTO RICO. The font is long primer. There is a variety in which the upper serifs are truncated in the vertical plane. This may be the case of your stamp. Described by Georgr Hill many years ago. Other possibility is that it may be a counterfeit overprint. Hard to tell without a closer look. See my future article in "Possessions" the journal of the US Possessions Philatelic Society. I describe multiple counterfeits.
