Most of the Paulson fracs you’ll find will be hotstamped and on the THC mold. The HS chips are on the RHC mold. Likely most people in that situation look to relabel another chip for their frac.
I just looked and realized that the HSI $1 and $2.50 were on the THC mold... so I guess you could go either way. I still think a relabel is likely best.
