Pat, the top one is one of the many made showing the crests/badges of different bits of the armed forces. I have a maroon background Lancashire Fusiliers one, and Mum has an blue background RAF one, in the same size as yours, and I've seen them with all different badges on and in different colours. I suspect (though do not know for sure) that they were sold via the NAAFI - perhaps one of our ex-services people could confirm? I've also seen them with different county police authority badges. No idea if they are Chance or not but there are usually several on eBay at any one time and they seem to always sell.
The bottom one looks similar to one Mum has (hers is a 6" square one) showing a map with a pointer and business name - most likely produced as a promo giveaway for the company concerned. Again, no idea if they are Chance, but David may well know more about them.
