What do you do with tropheys?

My kids have So many tropheys, & they are cluttering up his room… if i box them up its just gunna take uo space & will they even want them when theyre grown? My old tropheys my mom boxed up i didnt even take with me when i moved out, theyre still at her house! Do you really keep every trophey? What are ideas to do with them that wont be so much clutter
