Man its great to see so much new activity in this thread again, especially since this is now one of my favorite autistic fascinations. Anyways recently I've gotten a very large interest in both the circulated and uncirculated mintage of the commonwealth of the bahamas. The coins tend to have a very beachy theme and some of the silver designs that did not go into circulation are just beautiful. As of now here is my current collection of uncicrulateds and almost uncirculateds;

Perhaps of all the designs I own right now I would say I probably adore my 1974 .800 silver dollar coin the most (catalogued as km65a). Its actually interesting, the image they use on numista is actually significantly worse condition compared to the one I own:

One of the ones used in their actual currency didn't show up as well as I wanted to so I took a close up shot:

There still are some designs I want to add to my collection, however the information and/or listings of these even existing is hard to find if not non-existiant.
The first one is a special edition 1993 edward teach (blackbeard) five dollar coin (.925 silver). Something like this I would presume would be something of a fantasy coin but the fact this was a legitimate mintage fascinates me immensely;

The other one is a tad more common but I find the design of the whale to look beautiful. This is an 100 dollar coin also minted in 1993 made of .999 silver known as Cetacea-Blue Whale or its catalog number KM# 163. From the information provided, it only had 750 minted;

I'm absolutely terrified of being ripped off with ancient coins, especially ones that look so good, any tips you can share for making sure they're the real deal?
I think if you go for obscure ancient coins and not the ones that everyone seeks out then you may have a better time at finding ancients. Think of it like counterfitters for paper money. Sure there is the exception like that one guy who duplicated two dollar bills as people kept them as momentos but it is more likely than not they are going to mainly go for shit like dollar to five dollar bills since they are the most common. In the case of coinage I would expect most to try and replicate greek/roman issue coins but not something like swedish/dutch for instance. I don't own ancients but if I start collecting them thats probably how I am going to start.
