What is a reasonable bake sale price for holiday cookies?

I made some raspberry shortbread sandwich cookies for a Holiday bake sale and I’m supposed to bring them bagged and priced but I have no idea what to price them at. I want to make money for the fundraiser so I don’t want to under price them but I don’t want to over price them that they don’t sell.

These cookies are essentially two shortbread cookies with raspberry jam sandwiched between them and dusted with powdered sugar. The top cookie has a heart or star shape cut out so you can see the raspberry inside. These are pretty looking cookies and more time consuming since they rolled and cut out and assembled.

I think these could be one of the more higher priced cookies but I don’t know what price they should be. They are packaged four cookies per bag.
They are just over 2" scalloped circles.

How can i make these holiday cookies, and how much in advanced can i make my pies and cookies?

I love making foods for the holidays, and i usually make my apple pies and hand them out to people i know…. but this year i would like to make my pies and cookies in advance…. how long can i leave my pies in the freezer after i make them if i want to put them togetehr in advanced…. this way all i have to do is bake them.
