I want to share this Numista webpage information with you - https://en.numista.com/catalogue/pieces7634.html
Very nice pickup. Gem quality, I'd say. I like FAO issues. Got this one in a bulk bag and was delighted, since we lived in Tanzania for a year when I was a kid and I used to get one of these for my weekly allowance.
Cool coin. My wife is from Guyana so I've tried putting together a set of vintage/modern coins such as this. She couldn't care less lol
Numismat - do you have one of the 1978 Royal Mint 5c? Not the FM. Or the FM uncirculated 5 and 10 dollars of 1977-80. I have never seen these last ones.
No I don't generally collect anything past 1960 or so. The set I wanted to put together was just typical common circulating pieces. I did see your thread about the 5 cent coin, very cool and under-appreciated find
As funds for collecting dwindle, we can find some esoteric bits occasionally that are quite fun. I have been trying to run down those higher denomination Guyana FMs in uncirculated. Some of the earlier groats are quite rare....
Best of luck with your pursuits, I know how hard it can be with some of these "unknown rarities" that few people are aware of or talk about.
