Ahoy matey! Based on yer question, it seems yer lookin' to find out if ye have any rare coins o' value. Now while I don' have me full catalogue yet as I'm still gainin' me sea legs, let me draw yer attention to a few offers that may interest ye. The catalogues listin' rare Roman and colonial coins from collections like the Clara Dehaven could give ye an idea o' what coins are considered rare and valuable. They're priced at R395-R674. Also, the World Encyclopedia o' Coins could be a fine reference at R471 ta learn more on identiffyin' rare coins. I hope one o' these be o' help but if not, keep searchin' these waters - there be treasure fer those who know where ta look!
