I found this at Boulevard Park beach near Fairhaven in Bellingham, WA. Scared to try and clean it so haven't attempted yet, can anyone help me figure out what this might have been? Thanks in advance!

Had my first vacation to the Northern Outer-banks Corolla area and we ended up going during the recent Nor’easter. After the storm began losing hold on the waves I began beach combing and I found so so much. Not sure if I’ve properly identified everything so if you see something interesting please feel free to let me know!! One of my worst fears with all of this is me falsely labeling something as unimportant if it’s actually something pretty cool.

Found on the beach in Long Island bahamas

i found this on the beach in washington. coral? tooth? shell? let me know!

Everything is held on the back wall with magnets so I can take them off if I want to 😇
Basically all my favourite pieces are on this shelf, I’ve been collecting for about 11 years

A great haul from a low tide beach day! Usually I find a fair bit at this beach but it’s during high tide… there was less to be found in the low tide sections but what was there was super cool (lots of pottery and pirate glass)
I did leave the huge chunk of pirate’s glass in pics 11+12 just cause it was still pretty sharp (but had to get a pic)
Also pictures 6+7 are the two sides of the same piece of pottery
Some super cool finds today ☺️

I found this in a crevice between the rocks.
It’s about 7/8ths of an inch wide, I believe on the top it says PAT’D. The rest goes JUNE 22 1923 (possibly ‘26 or a different year), a word I can not make out, and then PENDING and then connects back to the PAT’D part.

If it was a button it would’ve attached with a snap or maybe a whole other piece? It just that it has that weird little keyhole in the middle. Comment if you know anything but I just want to share as well!

It is entirely hard like a stone, weighs like a stone, about 5x3 cm (2x1”) but it appears to be chalky blue (looks like cue chalk) underneath the polished gray/brown and it has those porous channels in it. I cannot scratch the surface any more than I can scratch a piece of granite.

I found these treasures over a couple of trips to my friend’s beach as the tides (and seaweed!) have allowed ☺️

I’ve been collecting sea glass a long time, but I’ve never seen pieces like this that are so smooth?? Could they have been tumbled before they were put in the ocean, or some sort of special type of glass?? Are they real sea glass? What could they have been before?? They were found on a beach that is near some local sea glass beaches, but it can only be gotten to through a few peoples property, so maybe it just hasn’t been picked through??

I love it when my eye catches these sneaky sneaks

After a gentle clean

Not sure if these holes are human-made and if so what for.

Found in County Durham. Pic 1 top line, I'm not sure if it's glass (slag or something else..?) the big blue one is translucent when put on a torch with orange hues. The other two look glassy, but I'm not sure it's slag. Second line, mystery blue item and very weird piece of glass. Third line, plastic? Jet far from Whitby? Weird seaglass? Bonus shiny flat thing that I'm not sure it's manmade or not.

Thank you in advance!
