It is a neat helmet that is hard to find. Some folks are inevitably going to fuss and question the reservist cross on the Griffin with it having the motto on the banner below. I personally think they probably did this (thrifty Germans?), but I also realize that some collectors don't like to see them set up like this w/the motto and the reservist cross together on a front plate. Just my 2-cents worth opinion, even knowing the helmet has never been in collector hands or messed with since being brought back from WW2.
A good judgement about the condition of the rest of the finish on the helmet obviously can't be made from the one photo that you have been provided for the helmet.
That being said, I agree with James, and have also personally witnessed that market prices have dropped considerably on quite a range of helmets. I recall that a really super nice condition Baden reserve officer helmet closer to the 1914 era didn't break the $2,000 mark last year on eBay. It was a beauty, and did not have any condition problems with the exterior surface finish on the helmet body.
It would be hard for me to swallow in giving it up if I was in your shoes and walk away from it, being that it hasn't been in collector hands before. But the daughter might find that she is going to "pound salt" with it on eBay if she goes that market in trying to sell it with what she "believes" it is worth. She'll find out the hard way that it won't bring what she believes it is worth on eBay, especially in this current economic world situation. Many buyers from Europe had enjoyed being able to buy helmets at a 25-35% discount for several years time, up until the past couple of months, because of the disparity in the exchange between the US Dollar and the Euro. I strongly believe that the old wide disparity that no longer exists at this current time had driven prices artificially higher for US sellers when they sold to European buyers on eBay. No offense intended to anyone in the EU, it is just a simple mathematical and economic fact. And remember that the Ruble has dropped considerably as well, taking many of those folks out of the buying market as well. With the current situation of a strong dollar the effect has been two-fold: it has leveled the playing field amongst US & European buyers, but it has also brought down the price of helmets and other collectible items because of the current strength of the dollar, because the Euro based buyers aren't willing to pay as much as they had been when the dollar was at 1.36 to 1.50 per Euro, compared to an amazing 1.056 dollars per Euro as of today's writing. So much for my economics 101 in a nutshell.
