Can you help identify the exact year of this 185X US Large Cent? [επιλυμένο]

Clearly this is dated somewhere 1850-1857. (Last date for this style is 1857)

Can you tell the last year number? It seems like its a 6 or a 0, but not sure.

I thought some experts here might know if other details only seen on an 1850 or 1856 could help confirm the year if the number itself is worn away?

For reference here is the numista entry for this:

Looks like a 6 to me.

I'm also seeing a 6.
