Is this for a gift? I have bought some really cool shadow boxes and made groupings for my husband's collection.
If they are part of a department, trading is how my husband gets his. The officers have to purchase these and usually will only give them up in a trade (patch for patch). You would have a much easier time if you have something to give - pins are a big deal as well.
PM and I'll send you a PD from my husband's department, he may be able to get fire as well.
