Is Numista Worth The Effort?

I use Numista everyday to research my coins - sometimes I use their forum to ask question about their site - quite helpful.

Numista is a Great resource to use.

Yes Numista is a good site , you can list all your coins and when done it will tell you what you have for countries and how many in each.

Medieval European coins have a ton of varieties, most of which are fairly rare. Valuations require multiple recorded values for the same variant; this is unlikely to happen in a field as immense as medieval Europe.

The rarity index values are just "how many Numista members have this". I suspect that most medieval European coins are not actually listed by any Numista members.

The missing info is usually just because no one added it yet; Numista is fundamentally a collaborative database.
It is also usually hard to add coins that aren't in any major references yet, which would explain why you're not finding anything new.

The ordering is generally by denomination and then by date, though they might have changed it recently. It can indeed get confusing, especially when denominations are nontrivial and/or entered incorrectly.

There is an intra-site search function, which mostly works.


On my own end, with a much more modern focus, I'm annoyed by the relatively recent (post-2020, I think) decision to merge the exonumia catalog into the main catalog, in a way that makes it strongly nontrivial to look for many kinds of coins without a gazillion irrelevant results for random tokens/medals/rounds.

This is unlikely to come up anywhere near as much for medieval coins, though.

I've had reasonable success using Numista.
