Albert Pillar of the Community United States 1805 Posts	Posted 02/03/2024 5:12 pm We sometimes see members post Chinese coin images for ID that are upside down. It's not unusual if not experienced. We may rely on published books, auction records, and online resources to identify coins. In the case of some Tibetan coins it can be hard to know which way is up? If just learning, it's important to get it right to know the date. In this case when using Numista the reverse of a 5 Sho coin having the cycle and year is shown upside down.

OzLeigh Valued Member Australia 215 Posts	Posted 02/04/2024 04:00 am Yes, you come across a lot of weird things on Numista. Do you really think this 1oz gold coin from Cuba has a diameter of 15mm? It must be extremely thick https://en.numista.com/catalogue/pieces257940.html Or this 2023 100 euro gold coin from France (31g, 15.55mm): http://en.numista.com/catalogue/pieces374932.html I suspect it is supposed to be a half ounce coin because the 50 euro coin from the same series weighs 7.78 grams with diameter of 22mm Edited by OzLeigh 02/04/2024 04:20 am Report this Post to the Staff
triggersmob Pillar of the Community Australia 7621 Posts	Posted 02/04/2024 04:16 am I remember seeing one coin with a diameter of over 2000mm. They missed the decimal point.

Albert Pillar of the Community United States 1805 Posts	Posted 02/04/2024 06:05 am I use Numista quite often. While much is good info, and helps a lot, there are a few times when something is at odds. So extra steps are needed to get things right before I embarrass myself by publishing wrong data in the coin project album pages. Report this Post to the Staff

jecz79 Valued Member Portugal 444 Posts	Posted 02/04/2024 12:43 pm Numista is kind of a wiki, uses public contributions. It is as bjherbison says. I only hope they remain an open site. These things sometimes go commercial and close access after collecting contributions. It looks like the most extensive web site now. Report this Post to the Staff
tdziemia Pillar of the Community United States 6896 Posts	Posted 02/04/2024 5:07 pm Thanks for pointing those out OzLeigh. I've contacted the editor responsible for Cuba suggesting a correction. Will do the same for the French type. Every catalog has good and bad features, and crowdsourcing has its own issues. As bjh says, everyone can help when they see a mistake.

"If you use Numista you should fix those changes when you see them. It's easy to create an account and propose changes." Yep. It's crowd-sourced. A couple of years back I bought a Titanium variety of a coin at a show from The Royal Mint that wasn't in the catalog. I took pictures and uploaded the data from the show floor. By the time I returned to my hotel room, the coin was added. -----Burton 50 year / Life / Emeritus ANA member (joined 12/1/1973) Life member: Numismatics International, CONECA Member: TNA, FtWCC, NETCC, OnLine Coin Club Owned by four cats and a wife of 40 years (joined 1983) Report this Post to the Staff
