Could these three items been used as currency? [opgelost]

Hello everyone!
Does anyone know of collectors of this type of thing? is there any value to any of these? they all are hand carved in my point of view, the 65 MM item could be Ivory, but I have no idea, the two small items could be sea shell of some sort, but again I don't know, my guess is they were used as money, I just don't know when or where that would have happened, any thoughts?
Thanks for looking at my stuff

Are you pictures made with a USB microscope?

Yes, should I get closer to them?

Here are some close ups

#1 Ivory? 65mm weight 2 grams


#2 Large white shell .24 grams


#3 small shell .27 grams

Thanks for te better pictures
I recognized the measuring scale
The first one could be bone, or even wale bone

To be fair, they could have been barter tokens at one point... but it's just as likely that the "tokens" were from a necklace or something. So I don't know.

The long stick like item is interesting, maybe it was the handle for something?

Thank you both, I knew it was a stretch to be able to tell if they were ever used as a currency, bone of some sort is interesting, oh well I'll just put them back into my unknown section of my collection

The long bone or ivory stick is a counter used in some forms of the game mah jong. Especially the Japanese form of the game. It's one of the betting sticks. Imagine a poker chip that looks like a stick.

It looks bone to me.

The long stick as a counter, I could see that, Thanks Oklahoman
