I know the 1st one is a Akragas eagle and crab coin, I'd like help determining its authenticity, and if possible, a more accurate I'd. For the second coin, I have no clue what It is, so a ID would be appreciated thanks for any help. The Akragas coin is 19-20 mm, and the 2nd coin(?) is ovular, around 20 mm from right to left, and 22 mm from up to down. The second one seems to be a coin from the boat(?) and faint lettering on the reverse.
The Akragas looks believable to me. Their bronzes must've circulated a long time because so many of them are extremely worn. The reverse of the second coin is probably a thunderbolt or winged thunderbolt. The obverse looks fairly feminine (but Apollos and Dionysos often look like women to me). Common combination, but I bet you'll find that it is from Sicily. Try searching CNG's archives with the search terms "AE, winged thunderbolt". You'll get hundreds of results but scrolling through them is quick. When you see likely matches, note what it is and try revising your search, plus then use the information to check other databases and resources. Also, it is better to show the larger picture in your post rather than inserting thumbnails which have to be clicked, and it is better for you to do the work of editing your photos to join them into one obverse/reverse image. Anything you can do to make it easier for CoinTalk members to help you will increase the odds of your getting help .
I can't identify the second coin, but TIF is right about the first one. It is from Akragas, Sicily and the three pellets below the crab identify it as a trias (denomination) of this type: https://www.acsearch.info/search.html?id=1872445 They both look genuine to me.
I can't see anything on the second reverse but would comment that the Agragas bronzes of the period are often worse than yours. The one ancientnut linked looks a lot better than most in terms of wear but is so off center/small flan that we lost the crayfish which is clear on your coin. There are several series and denominations of these differing on minor critters, dot count and placement but mint state ones of any are not easily found. Looking at acsearch, the highest grade ones tend to be missing something more important (to me) than detail lost to wear. I'd call your coin a keeper. Mine grades only fine by reasonable standards but, like yours, has all the critters. Your second obverse show some detail despite the photography but the reverse was lost. Can you try again?
The second looks like a bust of Artemis Soteira, so maybe Sicily, Syracuse. If I could make out any of the letters on the reverse, even one or two, I might be able to nail it down. Can you post a better pic?
I'm leaning towards Dionysos with a thyrsos on reverse. Perhaps something like this maybe: https://www.acsearch.info/search.html?id=1595271
The Doug in the manger must point out that Steve's coin is defective. The undertype was a hemilitron with six denomination dots. The two dots that should be at the extreme left mirroring the pair on the upper right just did not make it on the coin. Pity. However, I can not recall seeing a better example of this coin. Some have stronger undertypes and some have no detail on the undertype whatsoever but have bold countermarks. Part of me wonders how the slabbers would grade this one but Steve better not be caught submitting it. I'd be OK with a VG 6/5 5/5 (and expect them to label it the "Lagophagus Hoard"). Challenge: find one of these better than Steve's. When dealing with countermarks there is a lot of variety in placement, balance and even some room for opinions as to which characteristics are most important. My grade:
