What kind of gifts should we give to seniors in our co-ed service fraternity (Alpha Phi Omega)?

Me and my co-chair are in charge of doing senior wills. At this gathering we will be giving gifts to the seniors. However this is a co-ed fraternity, so the gifts that we would normally give girls (types of memorabilia, such as picture frames, gles, etc.) would more than likely not be appreciated by male members. What are some gifts that both would appreciate... or if that is too difficult... what are gifts that guys would like? I feel like the girls will be easy if we just have to give girls and guys different gifts... Also keep in mind that it'll have to be "clean" gifts, and can't have like references to things like alcohol or or drugs, we are a "dry" organization.
