The M.U.S.C.L.E. Figure Classification System was devised by Chad Perry of The University of M.U.S.C.L.E. and was compiled by using several sources including Soupie’s Color Image Archive and the help of lots of experienced collector’s input into the (now defunct) M.U.S.C.L.E. Database.
This guide incorporates all of the current M.U.S.C.L.E. figure data and presents it visually for quick and easy referencing of all the figures. It illustrates exactly what colours they were and were not produced in and also categorizes their available colours into 3 groups: Class A, Class B, Class C. These groups help differentiate how common or uncommon each of the colours are.
The guide is based on the 9 main colours. Colours with a box around them indicates the figure was not produced in that colour.
Class C figures are the most common M.U.S.C.L.E. figures. All the Flesh poster figures and many of the coloured figures are categorized as Class C as they were released in two out of the three ‘waves’ that Mattel released (all-flesh, flesh & colour, all-colour). The 5 Grape figures have not been listed in this guide due to their small numbers, but for collector’s information these figures are ranked as Class C figures and are quite common.
Class B figures should be thought of as a transitional group of M.U.S.C.L.E. because an arbitrary number was required to help differentiate the groups. Many Class B figures could be re-graded to either Class C or Class A rankings. The appearance of one large colour figure lot could downgrade any one of these figures to a Class C ranking, whereas since the classification guide’s first conception, certain Class Bs that have not shown up could be upgraded to a Class A status.
Class A figures should not really be considered rare, but rather ‘uncommon’. As they do not show up very often they were most likely manufactured towards the end of M.U.S.C.L.E. production, thus the lower numbers in circulation. It is also safe to assume that they were mainly produced in Canada, further shrinking their numbers. Some collectors think that Class A figures should be classed as rare and indeed some figures truly are (Purple #153 for example). Even the less popular sculpts can command significantly high prices if it is a Class A colour.
