I've heard that raising a family will do that to you...

I'm not a coin collector but if I were collecting coins, I'd be trying to buy here (from collectors you trust or are familiar with). I used to buy banknotes from fellow collectors on a different forum & was very happy with the notes I received. I still find
ebay great but it does take some time (& energy) to discover who's trustworthy (& which sellers to pass on).
You may wish to try swapping coins (if you have doubles). Folks at Numista seem to be happy with that arrangement:
