A related issue happened to me. If you see them and you can prove that they are yours, you call your local police department immediately. They in turn will contact the local police department of wherever the seller is from.

Remember the vintage collection stolen from an older collector in Illinois? It doesn't matter who has them or how they got them...you are entitled to retrieving your property. You must contact the police.

If they were stolen from the clubhouse, you should have probably already filed with the local police down there. If you ever see them in the future, it can be referenced to the clubhouse case.

Hope this helps.
