I have agreed to take on a project of identifying 263 coins, including ancients, pre-post American Revolution, and various world coins in the 1800's. Can someone tell me what sites would be most helpful. Also, is there anyone here that reads Latin very well. Thanks.
A lot will depend on what country they're from and how precise you need to be. If you want to get down to catalogue references, in some cases a dot in a field or a crooked crown can mean it's a completely different issue (or even ruler). At that point you might find there are no websites that cover all the varieties, so you'll need to find someone with the relevant hardcopy reference. (Books are often specific to just a few years or rulers in certain countries). Some places to start: 1) Google (and Google images in particular). If you Google the legend, being mindful of spaces, you can often find out a lot without even knowing what it says or even where it's from. Often you will find the coin (or similar) on an auction or dealers website, where they will give you most of what you need to know about any coin that matches. (Bear in mind, sometimes you have to match everything exactly, even dots in the legend or ribbons on a banner, but sometimes each coin of the same type can look very different from the others, particularly ancients where manufacture wasn't so precise). 2) Numista https://en.numista.com/catalogue/index.php?ct=coin. It's not comprehensive, particularly for ancients, but you can search for e.g. a year within a country and it will give you a list of all the coins minted with photos. 3) Wildwinds http://www.wildwinds.com/coins/ric/i.html. It has ancient and more modern coins, although often you'll need to identify the country and ruler first - see (1). Bear in mind it does not have all the varieties, but it's helpful to look through to see what variations to look out for (e.g. slight differences in lettering or whether the ruler is looking left or right). Here are a few links to help explain how to identify Roman coins: https://www.all-your-coins.com/en/blog/antique/comment-identifier-les-monnaies-romaines http://www.wnccoins.com/0022.htm It might seem daunting, but after a short while you'll start to recognise them!
If you want to post a few examples we could get a pretty good idea as to how much of a challenge you have taken on. Most world coins from the 1800s on are pretty easy to identify, at least as general types. Some have a lot of minor variations. Lots of us here seem to enjoy practicing by identifying world coins, myself included.
Coin Talk has a separate Ancient section where you would be more likely to get help if you posted decent photos there. Some of the members there do not collect modern coins (say after 1500 or so) so do not read the World Coins section. https://www.cointalk.com/forums/ancients/ There are a million variations on coins made between c.600 BC and c.1500 AD. No reference book has them all. Some are really rare as in one or two known. At my level, if I go a week without seeing something new to me just from postings on Coin Talk, I am probably not paying attention. Ancient fans tend to like that part of the hobby but people who insist on complete, certain and easy catalog referenced ID's often tire of the subject and leave. Still, 99% of the coins you will see are from the most common thousand or so types so the chance of getting help is pretty good IF you provide a good photo and all the information you can (size, weight etc.).
