I have recycled most of my sons' trophies to all kinds of dog match shows (=unofficial dog shows) most wagiest tail awards or dog obedience competitions similar side awards etc. Their have usually been metal and have marble base with glued or screwed metal plaques for gravings that have been easy to remove.
If the name can be removed, I think many organizations would be happy to take them and reuse them. They tend to be quite pricey considering they are actually to no use, take lots of space and are pain to dust.
(I of course asked my sons first, if they wanted to keep them and dust them themselves or recycle. Most have been recycled, both have kept only the most important ones. And when difficult child left home, he actually, over the year later, took total one trophy with him. I doubt he will ever take more of them.)
