  I have a planter I am getting ready to list and am confused.  It is 
identical to the one in my book, roseville floraline 502 on page 257 in my McCoy 
Pottery collector's referance book.  The problem is mine is marked on the bottom 
econline 502 USA. Is this the correct marking for this planter?  Thanks for the 
help in advance.
