Does PCGS grade Mameita-gin bean money from Edo Japan?

HKColonialCoins

Japan has a lot of little silver beans dating back to the 15th century. I have seen 1 graded example that is a Chogin, quite large most pieces average around 150g or more. https://www.pcgsasia.com/valueview/index?cid=4796&specno=629601

But I'm referring to smaller pieces, https://en.numista.com/catalogue/index.php?r=mameita-gin&ct=coin&p=1&x=0&y=0 such as these, and was wondering what are the, for lack of a better word, stipulations? requirements? minimum acceptable standards to send these in? Will PCGS grade these types and put them into slabs?

Thanks!
