So I was looking at my old coins and I noticed the 1918 reeded edge 20 cent is much rarer that the smooth edge. Mine looks very worn down on the edge but I think it is in fact reeded. Also the front is stamped with some sort of 189something and the back is double stamped with the 20 cent I believe. I read that this happens sometimes but never seen it like this. Opinions? I’m still very new. update: I have another one in the same year with a clear reeded edge but the same stamping issue.
What is that 1895 imprinted on the shield. Is it ink or stamped onto the coin? The 1920 seems to be the rare one. Check this site: https://en.numista.com/catalogue/pieces2276.html
These coins were all minted on top of older coins so seeing the 1895 showing through is not unusual. My Krause catalog says the edge can be plain or reeded and doesn't distinguish between them in value. There is no separate listing for the different edge types.
What @Hiddendragon said. You're seeing the ghostly impression of the undertype (the earlier coin it was struck over), which was also a 20-centesimi piece of a different design. These are cool. I like them. It's neat that you have a readable host coin date. This is what the earlier host coin - the undertype - looked like before being overstruck with the new design.
Thank you for this information definitely a new favorite of mine! What kind of valuedo you think this could bring?
They're of relatively modest value- just a buck or so usually, as I recall. No, here - I looked it up. (I was behind the times again.) Two bucks in Extremely Fine (XF40). $15.00 in the lowest Mint State grade (MS60). While I can't see it well enough in the pictures to grade it, your coin looks to me like it is somewhere in the Choice AU (About Uncirculated) spectrum, between AU53 and AU58, in my opinion. As you can see, those grades fall between the XF column (@$2.00) and the MS60 column (@$15.00). AU coins are usually unpriced in the catalogs, but you can sort of extrapolate their values by reading between the lines. Five to eight bucks is where I'd put it, in the retail sense. Common coins, but cool. Yours is a pretty decent example.
That's data from the Krause Standard Catalog of World Coins, as seen on the Numismatic Guaranty Corp (NGC) website, specifically their World Coins priceguide. You probably have some learning to do about the grading terminology and abbreviations and such. Sites like Numista and NGC can help you there, but can indeed be confusing. The NGC World Coins priceguide is a handy tool but I'm afraid it's not terribly user-friendly, let alone by novices. Still, if you get used to using Numista and NGC, it will help you a lot. There is also World Coin Gallery, which can be quite useful. It's a pretty old-school website and I think fairly beginner-friendly. Between WCG and Numista, you should have most of what you need for basic identification, at least of coins with Western alphabets.
I consistently see people who don't sell these common coins quoting book values that just aren't realistic. I sold several of these recently for $1.40 on eBay, which is my minimum price I'll sell anything for. There's plenty of them out there.
