Is the Donald Duck "Bubble pipe" comic from 1938 hard to find ?

[Ola Martinsson (AS/EAB)]

I'm wondering about the Donald Duck "Bubble pipe" comic from 1938. In The Gerber comics guide it is marked as a 6 in regards to the number of issues in existance, which would mean about 100 issues. This is the same marking as many of the early WDC. Yet I've seen the early WDC many times on ebay but I've never seen the "Bubble pipe" for sale there.

And is really the low value in the guide correct then ?

It would be interesting to  hear your opinions in this matter ?
