I realize that from a "technical" viewpoint, patina and corrosion are more or less the same thing (i.e. the same kind of chemical reactions...including the one that forms verdigris). So, my intent with the poll was to ask the question if this coin's appearance would rule it out from your collection (something like @oriole's or @norantyki's responses). I think collectors of ancients see a lot of green stuff on bronze/copper coins, but collectors of modern coins might be put off.

To me, the way the devices stand above the verdigris makes this coin attractive enough to collect.

Definitely not. I love that ash (AE diphthong) in the second pic. Kinda looks like it was drawn by a high school student.

Between POLONIAEs and FERRARIAEs I've got quite a few in my collection.

Whatever it is, I fall in with the "wouldn't mind having it in my collection" contingent. I like the look.

What IS this coin?

Also, echidna said sometimes it is active and needs to be removed. Even if it is active, how long would it take to really damage the value of this coin? It's taken quite a while for it to get to the point we see in this pictures. If it's going to take several more human lifetimes for it to damage the coin to the point it's no longer worthy of a collection, I'd let it munch away and enjoy it during MY lifetime.

Papal States - Ferrara 1 quattrino. https://www.NGCcoin.com/price-guide...duid-1485971

It's close to a U.S. small cent in size. The obverse is the papal tiara and keys over the coat of arms of the Lambertini family. Reverse is mint name and date (larger denomination coppers give the denomination reverse)

For that particular coin I find it attractive, it highlights the design and brings to mind the patinated bronze statues and copper roofs of the era.

Poll Question
What is your initial reaction to this coin? Don't overthink your choice, but please feel free to add comments!


Whatever you want to call it, corrosion, verdigris, toning, patina.....................mother-nature is taking it back.

Thanks for following my suggestion of registering an initial reation . Probably an American thing, but we've got this big statue with the same stuff (@DBM said as much), that we are quite used to ...

@MOS, yes indeed, and I think @twslisa said more or less the same thing.
Pretty sure I will be even greener than this coin 40 years from now, when its next owner might observe it and wonder about is appearance ... and maybe even post a similar question here

A truer statement has never been spoken here. "EVERY" coin on this forum will be in someone else's collection one day!

Not my area of collecting, but I like the look. It seems stable enough, at least for years or decades.

Chemically speaking, patina and corrosion are exactly the same thing.

As you see it, grade and value this one for what you think it may be worth.
(actually I do that with all coins.)

I collect World coin al all centuries and cultures, an so if it came my way at a reasonably (very) low cost, I would consider buying it.
My intention would be to fully investigate the history behind it, and write a short statement on the 2x2 which would hold it - in tiny lettering.

Well my initial reaction (since you said don't overthink) is that coin needs help. My second reaction after looking a little longer is wow that patina/corrosion on this coin is kind of growling on me.

I would not have a problem with this coin in my collection.

Thanks to everyone for sharing their thoughts.
Two final comments:
1. I did buy this coin recently, at a very reasonable price,in an ebay auction. I had bought a 1744 of the same type at an auction about a month ago, for twice as much. It too has some greenish-white deposits on the obverse, much less uniform.
2. Here is the label on the ANACS slab, which likely turned off some potential bidders
