2019 Panini The National Multi-Sport Forum

Have a Josh Allen memorabilia card I got with some cards from a Break that was done at this show. They randomed packs from The National to people in the break.

It's a memorabilia card but it's numbered 6/15. Was his card from the base Memorabilia set numbered, or is there a parallel numbered to /15?

If it helps the effect on the card is a basic shimmer effect. Anyone have any idea what insert this is from?
