If it were me, I'd take the time to research some of the badges. the higher numbered badges - certainly any battalion numbered higher than '100' and maybe even some of the lower numbers can command a good price, as the later units recruited fewer men to begin with and were almost all rolled into the lower numbered units as reinforcements when they hit the UK, so some of the badges are quite rare.
Here are some current prices [in Cdn. dollars] from Arctic Medals in western Canada. i've dealt with the man [selling] and he seems like a straight shooter. The prices here - cap badges unless otherwise stated - are his
selling price, so I'd guess you might get 50-60% of that selling. but don't quote me!
103 – cap badge $35.00, shoulder title - $40.00
108 - $90.00
183 - $40.00
184 - $100.00
229 - $90.00
44 - $75.00
68 - $65.00
