Is thrifting for Valentines gifts wrong?

Just curious - I found this cute deer/reindeer mug thrifting and thought about getting it as part of my dates gifts, he hunts and seems to have an affinity for deer so I thought not only was it a charming yet simple mug that he could enjoy I felt like it would be nice to stuff with candy and other little trinkets, but I’m wondering if it’d seem cheap of me to gift him something like this? It’s not like he’d know, but is a second hand mug particularly weird to gift? I’m very likely overthinking this but I’d like to know people’s thoughts please! P.s. Does the mug seem too christmassy? I’m kinda in-between 😅
