Hello all, I have a 1914 YSK, 1920 YSK, 1927 Memento and 1914 half dollar. Are they worth PCGS slot?
I have done some researches and I think the 1914 half dollar and the 1914 YSK dollar are worth PCGS?
I used a 10x loupe to look for scratches, dents, errors and etc
1. 1914 HALF Dollar: it should be AU55? Very few scratches or dents. Its in pretty good shape OBVERSE, it has couple PVC spots on REVERSE
2. 1920 YSK looks like a facsimile, its weights at 23grams.
3. 1914 YSK looks like a common date YUAN NC. It have lots of scratches and dents. Im actually not sure if its worth it to PCGS it. I think it'd be a F to XF only.

4. 1927 Memento looks like a common date. Has lots of scratches and dents. The only nuance is the OBVERSE side vines seem to be DD like :http://www.pcgs.com.cn/ValueView?cid=4207&specno=509213
