1928 R Italia Bvono DA L1

Nice coin. I've always liked this type.

Here is the same page that @alurid just linked, but with your coin's date highlighted.

It catalogs $20.00 in XF40 and $100.00 in MS60.

Yours appears to maybe have the slightest bit of rub on the high points, which would make it a choice About Uncirculated example (AU55 or so, I'd say).

If it were sent off to a grading service and did grade out as a Mint State coin, it would be better than MS60- more like MS63, if you're lucky. Then it's a $300.00 coin by the catalog, but unlikely to fetch that much in the real world.

But that's a somewhat wishful scenario. As mentioned, I believe it is an AU coin, so it would most likely fall between the $20.00 XF40 value and the $100.00 MS60 value.

My guess? $45-50-ish, retail. Take that with a big grain of salt, though.

I'd advise you try a little acetone or rubbing alcohol to see if you can remove those fingerprints, but don't dip it in any other kind of cleaning product or scrub it too hard. Just a gentle rub with a Q-tip, then a rinse with distilled water.

Here is the Numista page for the type, which has some additional information. Note that their listing "has the numbers mixed up" and puts a higher value on VF than XF, which is absurd. That kind of column-mixup glitch usually happens on the NGC/Krause pages, as @alurid noted. The Krause Standard Catalog of World Coins crew is understaffed and obviously don't have many people to proofread their catalog.

"BUONO DA L.1" is "good for 1 Lira", as you might have guessed.

 

Oh, for 18 bucks, most definitely. Good grab. The rubbing alcohol or acetone might not do much to help with those fingerprints, if they're old, considering this is a nickel composition coin. It might be too late to do anything about that, if the fingerprint oils have reacted with the coin's surface. You might just have to live with them if that's the case. But they're not too awful in any event.

 

That is the whole list. Usually you will get only a few grade columns for each type; seldom more than four or five. Sometimes they'll skip grades. Frequently you're lucky to get Mint State grade data at all for certain types. And don't get me started on the errors and glitches in their database!

One just has to extrapolate. Literally "read between the lines", if your coin's estimated grade falls between two columns.

Take About Uncirculated, for example. I cannot recall ever seeing an AU column listed for anything in the Krause Standard Catalog (from which the NGC data is derived). For AU, one has to extrapolate between the XF column and the first MS column listed.

For coins whose grade is well above the top grade listed (as in this case, if you hypothetically had an MS65 but MS63 is as high as the listings go), then looking at closed auctions is the best- often only- indicator.

Also, one must remember that the addition of US-style Sheldon scale numerical grades is a relatively recent addition to the Krause catalog. If I remember correctly, only the sections for US and Canadian coins used to use Sheldon grades like "XF40", "MS63", "MS65", etc. Everything else listed in the book was just the older, simple adjectival grades without numerals (VG F, VF, XF, UNC, and BU).

 

Congratulations, that is a truly beautiful coin. I've had some in the AU to lower MS range, but not of that quality.
