First of all, no offense, but most of your cards are crap. Now, there are a few good cards amough them, to be specific:
mirror force(20-90 depend on edition, condition, pack etc etc, u need to look up the card using pack code and edtion terms)
metalmorph(5-30, good card, old ones cost like heck~~)
magic cylinder, if you are certain it’s a SE and not a limited Edition junk, I would give 15-40 rating depend on condtion, edition(1st or unlimited)
Harpies’ feather: 5-20, depend on again, edition condtion etc.
Raigeki, same as harpies.
Jinzo: if it’s tin one, u got urself 10 bucks. If it’s a pack job, oh boy, u might have 30+ bucks on ur hand if it’s 1st edition in mint. although it’s easier to get a common now and is depreciating in players(not collectors)

rest of the stuff, you will be lucky if any of them sell for $10 each, unless some stuff(like gimini) is a real Secret Rare, and is first edition(and is blahblahblah) most of the stuff thou seems like starter deck stuff(Seriously, u got the entire sets~~~ relinquised etc) and worth either 25 cent(deck) 1-2 bucks(normal pack, non-first edition) or 5(pack, 1st edtion, and a better card than most)

next time when u ask this, look for the pack/deck note on each and edition note. It’s between the pic and the text (3 letters and a dash and a number is the pack note, it’s on right, the edition is on left… I think…. mayber other way around~~~) label clearly. A card that looks same in every other way might worth 2 bucks or 200 depend on edition/orgin… (ok, so it’s a 10-75 thing most of time… give me a break)

Your best, most expensive card is Mirror Force. It could be worth anywhere between $20-$50 depending on what set it is from and what condition it is in. You said it was GH, which is an Ultra Rare. If it is the Ultra rare from the MRD set, then you have yourself an expensive card there as long as it is in mint condition and 1st edition. It could be worth more than $50 as that is the original Mirror Force and is very hard to find nowadays. The rest of your cards are garbage really. Some of them are pretty good cards, but are either banned or Starter Deck cards or promos that aren’t worth anything. Actually as I look over your list I noticed that you also have a Metalmorph. If this is the original Metalmorph from the Playstation game, then you have a card that is worth more then Mirror Force is and is even harder to find. It could go for anywhere between $30-$70, yet again depending on mainly condition as it only came in one set. It’s set number is FMR-003. The other one is maybe worth 2 bucks and is set number PP01-EN014. Other notable cards would be Gemini Elf (assuming it is the actual Secret Rare and not the promo) and Millennium Shield, which could both go for around $20 each.
