Good day Smoothwood,
The problem, if one wants to consider it one, is that after a while on this and maybe other military collecting forums, you will find that the members have had bad experiences giving values to badges, only to find the fellow wants to flog it or it turns up on eBay or some other sales site at a ridiculous price. This tends to leave a sour taste in everyone's mouth and makes some "gun shy" about giving a hard and fast figure. I tend to think this has been caused by TV shows like "Antiques Roadshow" (both UK and US versions), "Canadian Pickers", "American Pickers" and "Pawn Stars". Some want to make a ridiculous profit off of everything.
The other thing is that value is a relative thing. What one wouldn't pay a nickel for, another would sell the farm to acquire (if he really needed it for his collection). Also, some might be too shy to jump in first, for fear of being refuted by another. I have broad shoulders (and have been thrown in cells of the Guards Depot in Pirbright), so I'll lead off by saying that you probably did not do too badly with your purchase. Neither scoring a treasure for next to nothing, nor being taken to the cleaner for three pieces of s**t. I get that you are new to this and are still on the uphill climb of the learning curve.
Finally, if you hang around this forum (having not been scared off), you will find that some of the members here have a certain point of view and certain things drive them around the bend. Their view is that study, research and willingness to learn should be the hallmarks of collecting, not just amassing a whole bunch of stuff so you can say "Look what I got!!". Hopefully, you have a thick skin and can let most comments slide like water off the back of a duck. I also got it right off the bat that you are new to the forum (and possibly to badge collecting), so I'm certainly willing to cut you some slack. I've been collecting for over forty years and have made my share of mistakes in that time. I see it as my task to help along the new collectors with my knowledge and experience if I can.
So, welcome to the Forum. I look forward to seeing images of your collection and future acquisitions. Stay safe and have fun!
