The main hazard of dealing with and identifying toy coins is the size, so it unsurprising that variations were missed in the publication in 1990. The expansion of this section alone increases the number of variants by at least a factor of 3 often 4 for each number assigned to it by Rogers. Does it matter? well I hope that by looking something new is being discovered and sometimes things shock me and I discover things under my own nose I have missed. As Rogers remarks there are a number of punctuation difference reported presumably not seen by him but there is a wide variation in the modelling and layout. He also wisely adds ""Others will probably be found". Rogers 1990 Galata Pub. page 46
I find it fascinating that one set the PRINCE less set shows such variation along with the ones found also in the USA hidden inside the smugglers coin.
