I wear a silver chain around my neck...have for years. Two coins hang from the chain.  "Lucky" coins...  This morning, in the bathroom...while getting ready for work, the two coins "clunked" to the floor... I thought..."Rats...my chain broke...". I Picked the coins up from the floor...looked for the chain...expecting to find it there next to the coins.   Not there...in fact, it was still slung 'round my neck.  Now this chain has no clasp...the only way off my neck is over my head...and the only way those coins come off the chain is if it breaks...  The chain is intact...the coins are intact...  What gives here?  How did the coins come off an intact silver chain?  I am at a loss to explain this...anyone with any thoughts???  Thanks...
