Send it to me. I'll hold it for a while and give you an unbiased opinion. Or send it to Wexler or Diamond for their opinion. But I'm afraid that no matter whose opinion you might get, it'll certainly be wrong.
Trust me, I know what your saying is more than likely true but dont flood these forums with Edited~ Language rules/ Please read , symbols to fill unacceptable words, is not allowed.
Testing specific gravity/density can be done as here: http://gemologyonline.com/Forum/phpBB2/viewtopic.php?f=37&t=15506 But if requires a good scale and a measuring set up. If it isn't a pure metal or a well known alloy, it is difficult to show anything as proof of %, but comparison with a regular cent of that year could show if it is normal metal consistency as far as %.
No.. in actuality the double LL in the Spanish language is pronounced like the letter Y.. so it's actually ONE DOYER
The weight of a normal cent coin (zincoln...or whatever) is 2.500 g. Your coin doesn't appear to be anything more than a well struck cent. First step (after you have absorbed - with good grace - the abuse here) would be to take it to a coin shop (or more than one) and get the opinion of someone who deals with coins on a daily basis and can see it in-hand. Actually you have the good wishes of all here that you have something REALLY different.
Appears to be a scarce PL cent (proof-like). I have a few modern Zincolns that look like proofs. Other than that, based on the weight and pictures, this is a normal cent.
It's difficult to judge a coin by a photo but my best guess is that it's a mint set coin struck on a burnished planchet.
