Very Rare Coin? With Ship And 2 Heads Roman

Hello All,

Ive got this coin in my collection. Which is probably from the same time as the other romans I previous posted. So I did some research. And it has alot of similarities to this coin. I post aswell an screenshot from MCSEARCH.info

It looks like this one description below. But then it is highly rare. Is this possible?

The quality is bad but it looks like the only similarity with 2 heads and an ship on the reverse. If I'm correctly. I hope someone can tell me more about this one.

Here below the description I found. I post aswell a few pictures of mine and the pictures of the coin ment here below to compare. Hope to hear from you!
I post 4 pictures of my coin. 2 from an distance and 2 from close by. For better comparing. And the one from the information below.

The Roman Republic
Struck Coinage
CN COR and dolabella series
As, Spain circa 120-115, Æ 47.70 g. Laureate head of Janus; above, mark of value. Rev. CN·COR Prow r.;
before, dolabella and below, ROMA. Sydenham â€". T.V. Buttrey, NC 1964, pp. 125-128. Crawford 81/1.
R. Russo, Essays Hersh, pl. 18, A (this coin). Exceedingly rare, only very few specimens known. Desert patina and in exceptional condition for the issue, and extremely fine The series with the dolabella, together with the as of Cn. Cor., were previously dated to 211-208 and attributed to Sicily. They are, in fact, struck in Spain between 130-128 and, together with the Sex. Iuli as, which is contemporary and also struck in Spain, represent the restart of the coinage of the as after a break in the issuing of this denomination after 145. The Sex. Ivli and Cn. Cor/Dolabella series were, up until the last twenty years, known in only a very few specimens, and thought to be unofficial issues. A number of new specimens have come on the market, primarily from Spain, and it now seems that these series are at least semi-official. Roberto gives his views on the dating above; I have always found them to be interesting coins, and am pleased to be able to offer a nearly complete group. (RBW
