Narrative:

I copied the wrong altitude on widebody transport and coordinated that altitude with ZNY. I coordinated FL390 and the aircraft crossed 2330N/6315W at FL350. We had no radio communication with the aircraft nor were there any arinc messages. I did not find out that the aircraft was at the wrong altitude until I called new york and asked if he had progressed 2330N/6315W at XX48Z.
