OP is in the Philippines. Sometimes it's worth just taking 2 sec to check someone's profile to see if they've shared their location instead of just blindly assuming US, so as not to offer well-intended advice which doesn't travel well internationally.
Because I'm not familiar with popular trading outlets in your country, I can't offer relevant advice.
In the UK it would be just straight onto eBay and see what it brings, which would be around £100 to the right collector, if mint.
