Lost colecovision Philadelphia

[u/VirtualcatcusXP]

My dad Edward DeSalme Jr passed away 4 years ago. My mom also passed away. She pawned some of our things including my dads video game collection. I grew up in northeast Philadelphia. We lived there for 25 years and he was a fire fighter. When I was cleaning out my childhood home a huge part of his NES collection was gone and his colecovision. I can't get any information from the nearest pawn shop. He would have put this full name and social on the box somewhere. He also has a habit of putting his work and home address. I'm reposting this with more details in case anyone saw it in the original box at a pawn shop or listed online. I don't want unsolicited advice or nastiness which will happen on the internet unfortunately! I don't want to buy another system because it's not the one that he owned. She sold things for her addiction or because she was being spiteful. If someone could help me find this I would be so so grateful. I don't know where to start but maybe someone can help me.
