Often when I've made a trade or even made a purchase for the sake of filling a hole I've thought... nahhhhh I'm not going to like this.
To give you an example, I bought a collection/lot off a guy for a considerable sum because I wanted the bank notes. His coins were the dead opposite of mine,
Royal Canadian Mint and US Mint collection type proof stuff in boxes and cases. I sold most of it and it did quite well giving me a heck of a deal on the chartered bank notes.
But there's a couple I didn't sell and they kind of sucked me into the others of their series.
Item One
US Mint boxed sets with the encased in plastic
State Quarters... I know I know, but I REALLY liked how the quarters looked so I bought the rest of them. I have no idea what the attraction was but I liked the designs and strike of the specimens. Maybe because I'm not exposed to it all the time.
Item Two
Royal Canadian Mint Dinosaur Fossil four dollar silver pieces. The original lot I purchased had the Parasaurolophus fossil and I was just going to sell it since it was going for a fair bit over purchase (though not as much as now). I mean it's just a mint issued AT coin right? Nope. The darn thing grew on me and I bought two more just like it to compare them. Every one of them is unique in appearance and I have four sets of four now but I had to lay off when the prices skyrocketed.
so many coins so little money....
Please chime in with coins that "grew on you"
