Here are some more goofs I have noticed.
1) In the scene where they discover the counterfeit bills, you can see Stef try the phone in the background to see if it works. She puts it down right away, meaning, presumably that it doesn't work, but later, Chunk calls the police from that same phone.
2) The skeleton organ scene: After Andi makes the first mistake, the left side of the floor falls away from underneath Mouth, but in the next aerial shot, when the other side of the floor falls away from underneath Brand, the left side of the floor is still there. Also, Mouth has been standing on the left hand side of the organ the whole time, but when Andi is finally able to lower the bridge, we see him on the right side of the organ.

When the Goonies are going down the water shoot to get to the ship you can see spikes suspended above as booby traps, when brad is filmed going down he hits several of them and they all move like rubber.

In the attic when Mikey is holding the map, still framed, he calls Chunk and Chunk says "I didn't touch nothing". Right after Chunk's reply Data says to Brandon, "Don't touch it Josh" which is Brandon's real name (not movie name).
When Chunk is in the freezer with the dead Fratelli brother, the dead guy falls on him a number of times, one time, he clearly blinks.

At the end of the film when Andy has to play the piano notes, the final note she is unsure of. She comments that "Is it an A sharp or a B flat?" This is exactly the same note on a piano, so it would make no difference.
However, this was an intentional gag on the part of the writers, not a goof.
When Mikey leaves his house on the bike, he is wearing a yellow raincoat. He continues to wear this raincoat until the Goonies are in the "pipes" scene. One minute, he is wearing the jacket, the next it is off.
In a deleted scene, Stef and Mouth are tied together to walk the plank, Stef offers to share her breath with Mouth. In the finished film, he later thanks her for this, even though the scene was cut!

In the tunnels, when the boys find the skeleton of Chester Copperpot, they check his wallet to determine if it is really him. Mikey pulls out a baseball card and says "Lou Gehrig". Chester Copperpot died in 1932 or 1933, when Lou Gehrig was a great baseball player for the New York Yankees. However, the specific baseball card that Mikey pulls out is really a 1974 Topps All American baseball card of Lou Gehrig. If Chester Copperpot died in the tunnels in 1932/1933, how does he have a baseball card from 1974 in his wallet?

In the scene where the kids are in the attic looking around...The oldest boy turns on the over head string style light numerous times.....Each time they break away the light is off and he turns it back on again.....
During the scene where the gang is underground by the pipes and mouth tells them to start hitting the pipes, after mouth yells back pressure and troy goes in to the toilet stall, you can see the lift unit that pushes him up in the air during the water spout scene.
When Mikey's mother gets the jewels poured into her hand, she has pink nail polish on, but when she holds her hand up into the light she doesn't.
In the majority of scenes Chunk has the mole on the left side of his mouth, but in the scene when he's thrown in the back of the truck with the dead guy, it all of a sudden switched to his right side. This also occurs in another scene, i think it's the one when he first meets Sloth and is trying to give him chocolate.
When the kids fall out of the tunnels/waterslide into the water, they have a lantern that clearly goes under water and is still lit when they resurface!

In the scene where the Goonies discover the entrance to the tunnel, (and the fifty dollar bills!) Mikey yells at Brand, but mistakenly calls him by his real name Josh. Sean Astin brings it up on the DVD commentary.

When Mikey is talking to One Eyed Willy inside the pirate ship, his face is visibly brown and dirty looking. A scene or so later, when the Frattelli's catch up to them and force them out of the pirate ship, Mikey's face is totally white and clean looking.
When Mouth is walking Rosalita around translating to her, there is gel in his hair, but as he walks down the stairs with Mrs Walsh and Rosalita, his hair is all fluffy.
Up in the attic Mikey calls Chunk to hold the framed map for Chunk to drop it. Once Chunk does drop it, Mikey picks it up and tosses all the broken glass off. But when the rest of the boys gather to see the map, all the broken glass is still on top of it.
In the scene when Chunk intercepts the Fratelli's from the side of the road, after he states they have had a run in with these "disgusting people, the Fratelli brother Jake turns on the ORV's interior light and you can see his reflection in the side view mirror, taking a drag off a ciggarette. As the camera stays on Chunk, he starts to say the Jewish prayer. The camera cuts to Jake and he begins his operatic verse. Cut back to Chunk screaming... The image in the side view mirror of Jake taking a drag off the cigarette is replayed... As he is heard singing! How does one sing and inhale cigarette smoke at the same time?
During the scene where the goonies were rescued they're all being interviewed. Data says the scariest moment was being attacked by the octopus, but the octopus scene was cut from the finished movie.
In the scene where Mikey asks Chunk to hold the frame with the map; When Chunk breaks it they toss off all the broken glass from the map. The very next scene, they slide the map from under all the same glass they just tossed off the frame.
Rosalita did not speak English. How come she can understand the foreclosure situation and in the even screamed in Spanish not to sign?
When the kids find the ship and the caves are collapsing, you can see rocks falling from the ceiling that land on the water and float! -Pure polystyrene (or styrofoam).
In the scene where Mikey's dad rips up the foreclosure and throws it in the air, you can clearly see someone throw another handful of paper up a second after him. I guess one document wouldn't create enough confetti for the camera.
In the basement scene of the goonies when Mike slams the ground with the pole to see if anything is buried, Brandon says " There's nothing buried under there ". Mike responds by apparently calling Brandon by his real name. " There is something buried under there Josh "

When the Goonies are riding down the hill, they stop to look at the Doubloon and the coast line. Chunk says 'anyone got a candy bar, a baby ruth'? Later we see Chunk throws a baby ruth at sloth. Where did he suddenly get this from?
When Mouth goes to let the air out of his big brother's tires, as soon as he took the caps on the tire valves off they deflated. Taking the caps off won't deflate the tire, but we all know if you stick a screw or something in there it will deflate as you push in.

When Troy is in the W.C. reading a Guns n' Ammo magazine you can see that in the first take he has a different issue than in the second one (although they're both pretty similar). You can certainly notice they are different ones.
When you see the distance shot of the fire in front of the police station, you can see the logs they have used to contain the fire in a square.
When chunk is locked up yelling for help in the ice cream freezer, how come he yells for help then once the others have gone under ground he then lets himself out... Why didn't he do that before?
In the pirate ship scene after Sloth throws his mom in the water and then dives in the water, watch when the water splashes up.. its blue...
Right behind Chunk when they were in the bar with the Fratelli's, is a window and you can very clearly see a cameraman with his camera walking behind him and then duck down as he realizes he's in the camera.

When The Goonies discover the pirate ship, and as they are climbing the rungs of the shipside ladder, if you look to the far left of the screen you will see a man on the ship waving to someone.
Pretty sure it wasnt a cast member. I just discovered it and I am probably not the first to do so however I have found nothing about it online at all.
BTW This movie still makes me laugh after all these years.
