Austrian Silver Philharmonic. Why No Love?

I completely agree that ASE and Maples are more popular than Philharmonics. I look at my buying habits, until a month ago I never owned one. One reason for this was availability. The coin shop I frequent, never has any. The only reason they had on on hand was because someone sold some silver that included a Philharmonic. If I went to the coin shop another day, I may not have had the opportunity to pick one up.

hard to get usually but they are top notch

not a big fan of them because of their size (36 or 37mm diameter, smaller than even the maples), smooth edge, and too simplistic of an unchanging design)

So you do care about it? If you couldn't care less then you would care nil. Given that you "could care less" the only thing I know is you care more than nil.

The U.S. and Canadian markets know ASE's and Maples better, and are more familiar with them.

I would think the primary market for Philharmonic bullion coins would be Austrian and European collectors.

Same thing as U.S. coin collectors mainly collecting U.S.coins.

Pandas and Koalas and kookaburras also change every year and are very collectible above and beyond their bullion value.

I agree. Changing designs drive interest and add a collectability facet that adds to demand. Maple Leafs probably have the best of both world by producing the classic design in addition to collectible designs annually.
