J & E Mechanical banks - reproductions or original ?

Hello .  

I'm completely new to the vintage/antique world and need some help ! The banks I am attaching here I have identified as J & E Stevens and I'm fairly certain one of them is not an original ..however , searching on line I am finding many variations with a few looking like reproductions but selling as originals .. thus confusing me more .. I have not cleaned them other than to dust off some of the details ..and I'm worried I may hurt them in some way..  They are working and have no major visible flaws -  

Any help would be greatly appreciated .  The Bad accident one really has me stumped !  I have a lot of pictures and only a few allowed here so if you need more please let me know .  

Thanks so much for any help - I am selling off a relatives estate and having an idea of value will keep me sane as I sort through this unfamiliar territory :) :)
