Your physical cards probably aren't worth shit, but check sites like Trollandtoad, eBay and TCGplayer for the shinier ones to see if you can make a decent 5-10 bucks off them before you ask in the thread. We don't have the prices memorized for every single card.

To see what your PTCGO stuff is worth, look on the PTCGO forums in the trading section. For example, Top Cut Trading inc

Pack codes are worth about 15-30 cents while other codes are worth around a dollar or two.

Remember that if you're doing a TCGO code dump, post them as images and block off the QR codes. This prevents scumbags from scooping up the entire lot with client's QR reader or, in the case of typed codes, copypasting all of them onto the redemption page for themselves. DO NOT put text codes in a pastebin and remove the last character from them just because it's easier for you if you're dumping codes, scumbags have access to scripts that can easily find the missing letter/number.
